The single seedliners always fall back on Genesis 4:1:

“And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD.” (Genesis 4:1)

The New King James relates it this way:

“Now Adam knew Eve his wife, and she conceived and bore Cain, and said, "I have acquired a man from the LORD."

However, the single seedliners never pay any attention to the “;” after the word wife. In the King James Version. This “;” separates the first part of the verse from the rest of it. So Adam knew Eve his wife, but there is no proof that she got pregnant from that union. A man can have intercourse with his wife many times and not get her pregnant; or he can have it one time and she becomes pregnant.

Also in both verses she thought she had gotten a man child from the “Lord.” She did not say that she got it from Adam, but she got it from the “Lord.” Because she thought that Satan was a “lord” when he was talking to her and beguiled her.

How the single seedliners can say that the woman has seed that relates to Christ and then deny that the part about Satan having seed, is beyond belief. They pick and choose the parts of a verse they want to believe and discard the parts they don’t want.

Genesis 3:16 has many children coming from Satan, not just Cain. Which the single seedliners never mention. In fact, there are many sons and daughters of Satan, but they are not called that.

We find the first mention of them in:

“Certain men, THE CHILDREN OF BELIAL, are gone out from among you, and have withdrawn the inhabitants of their city, saying, Let us go and serve other gods, which ye have not known.” (Deuteronomy 13:13)

Now who is this Belial you ask? Well lets look at a couple of Bible commentaries and see what they have to say.

Belial:

[BEE lih uhl] (worthlessness); AN OLD TESTAMENT TERM DESIGNATING A PERSON AS GODLESS OR LAWLESS. The NKJV translates corrupt (1 Samuel 2:12), perverted (Judges 19:22), rebel (2 Samuel 20:1), scoundrel (1 Kings 21:10,13), worthless men (1 Samuel 30:22), and worthless rogues (2 Samuel 16:7). A "daughter of Belial" (1 Samuel 1:16), (KJV) means a wicked woman (NKJV, NIV), one who is base (RSV) and worthless (NASB).

BELIAL SOMETIMES TAKES THE FORM OF A PROPER NAME (or a personification), APPLIED TO A DEMON OR TO SATAN (Nah. 1:15). MANY SCHOLARS BELIEVE THAT BELIAL IS ANOTHER NAME FOR SATAN. (from Nelson's Illustrated Bible Dictionary) (Copyright (C) 1986, Thomas Nelson Publishers)

Belial:

BE'LIAL (be'li‑al; "worthlessness, wickedness"). Belial is often used in the KJV as if it were a proper name, but beyond question it should not be regarded in the OT as such, its meaning being "worthlessness," and hence "recklessness, lawlessness." The expression "son" or "man of Belial" must be understood as meaning simply a worthless, lawless fellow (Deuteronomy 13:13; Judg. 19:22; 20:13), see marg.; etc.)

In the NT the term appears (in the best manuscripts) in the form Belias, and not Belial, as given in the KJV. THE TERM, AS USED IN (2 Corinthians 6:15), IS GENERALLY UNDERSTOOD AS APPLIED TO SATAN, AS THE PERSONIFICATION OF ALL THAT IS BAD.

Belial occurs only once in the NASB and NIV (2 Corinthians 6:15). Elsewhere in those translations the Hebrew terms rendered "sons [or children] of Belial" in the KJV are given as "worthless men," "worthless fellows," or "wicked men," often with a marginal reading, "lit., sons of Belial." (from New Unger's Bible Dictionary) (originally published by Moody Press of Chicago, Illinois. Copyright (C) 1988.)

Belial:

(worthlessness): recklessness, lawlessness. Not strictly a proper name, but used so by personification. [Beli] = "without" and [ya'al] "usefulness," i.e. good for nothing. "A man of Belial" is a worthless, lawless fellow (Deuteronomy 13:13; Judges 19:22; 1 Samuel 2:12). Later [Raqa'] ("vain fellows" (2 Samuel 6:20), [hareeqiym]), and "Fool" were used instead: (Matthew 5:22). [Nabal] (= fool) is called "man of Belial" (1 Samuel 25:25) In the New Testament "Beliar" is the form in some oldest manuscripts (2 Corinthians 6:15) AS SATAN IS OPPOSED TO GOD, ANTICHRIST TO CHRIST, SO BELIAL STANDING HERE IN CONTRAST TO CHRIST MUST DENOTE ALL ANTI-CHRISTIAN POLLUTIONS PERSONIFIED. (from Fausset's Bible Dictionary)

When reading on in the scriptures after Deuteronomy 13:13, we see that Yahweh orders the children of Belial destroyed, every man, woman and child and all their goods:

“Then shalt thou inquire, and make search, and ask diligently; and, behold, if it be truth, and the thing certain, that such abomination is wrought among you;

THOU SHALT SURELY SMITE THE INHABITANTS (Yahweh is saying here all of the inhabitants of the city, the men, women and children they are so evil) OF THAT CITY WITH THE EDGE OF THE SWORD, DESTROYING IT UTTERLY, AND ALL THAT IS THEREIN, AND THE CATTLE THEREOF, WITH THE EDGE OF THE SWORD. And thou shalt gather all the spoil of it into the midst of the street thereof, and shalt burn with fire the city, and all the spoil thereof every whit, for the LORD thy God: and it shall be an heap for ever; it shall not be built again. And there shall cleave nought of the cursed thing to thine hand: that the LORD may turn from the fierceness of his anger, and shew thee mercy, and have compassion upon thee, and multiply thee, as he hath sworn unto thy fathers; When thou shalt hearken to the voice of the LORD thy God, to keep all his commandments which I command thee this day, to do that which is right in the eyes of the LORD thy God.” (Deuteronomy 13:14‑18)

The men and women of Belial were and are queers as the following verse attests:

“Now as they were making their hearts merry, behold, the men of the city, certain sons of Belial, beset the house round about, and beat at the door, and spake to the master of the house, the old man, saying, BRING FORTH THE MAN THAT CAME INTO THINE HOUSE, THAT WE MAY KNOW HIM.” (Judges 19:22)

The man of the house asked the queers to go away and leave him and the man alone and that they should not do such evil.

“And the man, the master of the house, went out unto them, and said unto them, Nay, my brethren, nay, I pray you, do not so wickedly; seeing that this man is come into mine house, do not this folly. Behold, here is my daughter a maiden, and his concubine; them I will bring out now, and humble ye them, and do with them what seemeth good unto you: but unto this man do not so vile a thing. But the men would not hearken to him: so the man took his concubine, and brought her forth unto them; and they knew her, and abused her all the night until the morning: and when the day began to spring, they let her go. Then came the woman in the dawning of the day, and fell down at the door of the man's house (she died from the abuse) where her lord was, till it was light. And her lord rose up in the morning, and opened the doors of the house, and went out to go his way: and, behold, the woman his concubine was fallen down at the door of the house, and her hands were upon the threshold. And he said unto her, Up, and let us be going. But none answered. Then the man took her up upon an ass, and the man rose up, and gat him unto his place. And WHEN HE WAS COME INTO HIS HOUSE, HE TOOK A KNIFE, AND LAID HOLD ON HIS CONCUBINE, AND DIVIDED HER, TOGETHER WITH HER BONES, INTO TWELVE PIECES, AND SENT HER INTO ALL THE COASTS OF ISRAEL.” (Judges 19:23‑29)

When he sent the pieces of the woman to the twelve tribes, one can just imagine what consternation it caused them. It caused such a furor that they had a meeting of all the tribes to see what they would do, to these evil men.

“And it was so, that all that saw it said, There was no such deed done nor seen from the day that the children of Israel came up out of the land of Egypt unto this day: consider of it, take advice, and speak your minds.” (Judges 19:30)

So the Tribes of Israel had their meeting and it was decided that they would destroy the evil men that did this awful deed. They told Benjamin in the city to:

“Now therefore deliver us the men, the children of Belial, which are in Gibeah, that we may put them to death, and put away evil from Israel. But the children of Benjamin would not hearken to the voice of their brethren the children of Israel.” (Judges 20:13)

But the Benjamites would not deliver the evil sons of Belial to the other Israelites. And because of them not giving up the evil ones, the sons of Satan, the Jews who were called “Belial” all but a few of the tribe of Benjamin were destroyed.

Then because they would not hearken unto their brothers:

“And the children of Benjamin said, They are smitten down before us, as at the first. But the children of Israel said, Let us flee, and draw them from the city unto the highways. And all the men of Israel rose up out of their place, and put themselves in array at Baaltamar: and the liers in wait of Israel came forth out of their places, even out of the meadows of Gibeah. And there came against Gibeah ten thousand chosen men out of all Israel, and the battle was sore: but they knew not that evil was near them. And the LORD smote Benjamin before Israel: and the children of Israel destroyed of the Benjamites that day twenty and five thousand and an hundred men: all these drew the sword. So the children of Benjamin saw that they were smitten: for the men of Israel gave place to the Benjamites, because they trusted unto the liers in wait which they had set beside Gibeah. And the liers in wait hasted, and rushed upon Gibeah; and the liers in wait drew themselves along, and smote all the city with the edge of the sword. Now there was an appointed sign between the men of Israel and the liers in wait, that they should make a great flame with smoke rise up out of the city. And when the men of Israel retired in the battle, Benjamin began to smite and kill of the men of Israel about thirty persons: for they said, Surely they are smitten down before us, as in the first battle. But when the flame began to arise up out of the city with a pillar of smoke, the Benjamites looked behind them, and, behold, the flame of the city ascended up to heaven. And when the men of Israel turned again, the men of Benjamin were amazed: for they saw that evil was come upon them. Therefore they turned their backs before the men of Israel unto the way of the wilderness; but the battle overtook them; and them which came out of the cities they destroyed in the midst of them. Thus they inclosed the Benjamites round about, and chased them, and trode them down with ease over against Gibeah toward the sunrising. And there fell of Benjamin eighteen thousand men; all these were men of valour. And they turned and fled toward the wilderness unto the rock of Rimmon: and they gleaned of them in the highways five thousand men; and pursued hard after them unto Gidom, and slew two thousand men of them. So that all which fell that day of Benjamin were twenty and five thousand men that drew the sword; all these were men of valour. But six hundred men turned and fled to the wilderness unto the rock Rimmon, and abode in the rock Rimmon four months. And the men of Israel turned again upon the children of Benjamin, and smote them with the edge of the sword, as well the men of every city, as the beast, and all that came to hand: also they set on fire all the cities that they came to.” (Judges 20:32‑48)

The children of Israel slew so many of the Tribe of Benjamin that they feared that Benjamin would cease to be a tribe; so they went to Yahweh and asked how they could remedy the situation as they had sworn that they would not give their daughters to Benjamin for wives. And Yahweh told them what to do and they did it, therefore Benjamin remained a tribe in Israel.

The sons or daughters are mentioned also in the following scriptures: 1 Samuel 1:16, 10:27, 25:17, 25:25, 30:22; 2 Samuel 16:7, 20:1, 23:6; 1 Kings 21:10, 21:13; 2 Chronicles 13:7; 2 Corinthians 6:15. And every time they are mentioned they are evil and are to be eventually destroyed.

There is no doubt that these are the children of Satan, just as was Cain. They were the descendants of Cain.

Belial:

(be'‑li‑al), (bel'‑yal) (beliya`al; Beliar): This name, occurring very frequently in the Old Testament, has the sense of "worthlessness" (compare (2 Samuel 23:6); accordingly in such phrases as "sons of Belial" (Judges 20:13; 1 Samuel 10:27, etc.), "Men of Belial" (1 Samuel 30:22; 1 Kings 21:13, etc.), which the English Revised Version usually retains, the American Standard Revised Version more correctly renders, "base fellows" (so "daughter of Belial" (1 Samuel 1:16), "wicked woman"). There is here no suggestion a proper name. AFTERWARD, HOWEVER, “BELIAL” BECAME A PROPER NAME FOR SATAN, OR FOR ANTICHRIST (thus frequently in the Jewish (should be rendered Israelite) Apocalyptic writings, e.g. in XII P, Book Jub, Asc Isa, Sib Or). In this sense Paul used the word in 2 Corinthians 6:15, "What concord hath Christ with Belial?" (Beliar). Bousset thinks that Paul's "man of sin" in 2 Thessalonians 2:3, where some authorities read "man of lawlessness," is a translation of this term. The sense at least is similar. See ANTICHRIST; MAN OF SIN. JAMES ORR (from International Standard Bible Encyclopedia, Electronic Database Copyright (C) 1996 by Biblesoft)

We have this from another commentary on the word Belial:

David, "what a mean creature is he!" "Lord, what is man," may we say upon the reading of this story, "what a vile creature is he, when he is given up to his own heart's lusts!" THE SINNERS ARE HERE CALLED SONS OF BELIAL, THAT IS, UNGOVERNABLE MEN, MEN THAT WOULD ENDURE NO YOKE, CHILDREN OF THE DEVIL (for he is Belial), resembling him, and joining with him in rebellion against God and his government. (from Matthew Henry's Commentary)

So we can see that the Seedliners avoid the passages they can’t explain away, and hang on to those that can be explained and shows that their beliefs are fallacious.
