Be interesting to hear your answer to the question in Matthew 12:34 as to whom you believe is the spiritual father of the those referred unto as vipers in that verse?
Luk 11:14 And he was
casting out a devil, and it was dumb. And it came to pass, when the devil was gone out, the dumb spake; and the people wondered.
Luk 11:15 But some of them said, He casteth out devils through Beelzebub the chief of the devils.
Luk 11:16 And others, tempting him, sought of him a sign from heaven.
Luk 11:17 But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth.
Luk 11:18 If
Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub.
Luk 11:20 But if I with the finger of God
cast out devils, no doubt the kingdom of God is come upon you.
Mar 9:25 When Jesus saw that the people came running together, he rebuked the
foul spirit, saying unto him, Thou
dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.
Luk 13:11 And, behold, there was
a woman which had a spirit of infirmity eighteen years, and was bowed together, and could in no wise lift up herself.
Luk 13:12 And when Jesus saw her, he called her to him, and said unto her, Woman, thou art loosed from thine infirmity.
Luk 13:13 And he laid his hands on her: and immediately she was made straight, and glorified God.
Luk 13:14 And the ruler of the synagogue answered with indignation, because that Jesus had healed on the sabbath day, and said unto the people, There are six days in which men ought to work: in them therefore come and be healed, and not on the sabbath day.
Luk 13:15 The Lord then answered him, and said, Thou hypocrite, doth not each one of you on the sabbath loose his ox or his ass from the stall, and lead him away to watering?
Luk 13:16 And ought not this woman, being a daughter of Abraham,
whom Satan hath bound, lo, these eighteen years, be loosed from this bond on the sabbath day?
To answer your question, in the old testament, it is written that Satan "spread himself out", or "multiplied himself".
Eze 28:14 Thou H859 art the anointed H4473 cherub H3742 that covereth; H5526
One meaning for anointed is expansion.
Or as defined in the dictionary, "
The act of increasing (something) in size, volume,
quantity or scope"
And some of the definitions for the word "covereth" is,
to entwine as a screen; by implication to fence in,
cover over, (figuratively), hedge in,
join together,
When Jesus asked "How can Satan cast out Satan?", He was referring to demonic spirits that were from and of Satan. Offspring, if you will, of the devil.
The devil increases himself and is in them and they in him, even as the spirit of God increased Himself from Moses to the seventy elders.
Num 11:25 And the LORD came down in a cloud, and spake unto him, and
took of H4480 the spirit that was upon him, and
gave it unto the seventy elders: and it came to pass, that, when the spirit rested upon them, they prophesied, and did not cease.
The word "of", literally means, "a part of".
In other words, "The Lord... took a part of the spirit that was upon him (Moses), and gave it to the seventy elders."
Which means, the spirit that was on Moses had offspring, and therefore multiplied itself.
And as that which is done to us is done to Christ, so it is with the children of the devil.
Mat 25:40 And the King shall answer and say unto them, Verily I say unto you,
Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
Act 26:14 And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou me? it is hard for thee to kick against the pricks.
Act 26:15 And I said, Who art thou, Lord? And he said,
I am Jesus whom thou persecutest.
