Nag Hammadi.
In his arrogance, Yaldabaoth boasted to the other archons that:
"I am God and there is no other God beside me!"
Yaldabaoth was weak and ignorant, because he didn't realise that were any power greater than him. He thought he was the First. Yaldabaoth had sinned for saying these words, which was why he was called Samael – "the blind god". He has another name – Saklas, a name usually assigned to Satan.
It was Sophia, who rebuked him and gave him this name, Samael.
"You are mistaken, Samael"
After this boast, he challenged the voice:
"If any other thing exists before me, let it be shown forth to me!"
So Sophia stretch forth her finger and brought limitless light into matter and the region of chaos.
The chief archon trembled in fear.
When Yaldabaoth and the other archons heard the voice. They sought this voice and traced the voice to the abyss, where the chief archon saw the reflection of his mother in the water. They want take hold of the image but could not. They were ignorant and weak, because they didn't understand that the image was reflected from above.
"I am a jealous God, and there is no other God beside me."
But by announcing this he indicated to the angels who attended him that there exists another God.
For if there were no other one, of whom would he be jealous?
