Who is the God of Israel jealous of?

"14For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God"

"When he saw creation surrounding him, and the throng of angels around him who had come forth from him, he said to them, I am a jealous god and there is no other god beside me.

But by announcing this, he suggested to the angels with him that there is another god. For if there were no other god, of whom would he be jealous?"

"Then shadow perceived there was something mightier than it, and felt envy; and when it had become pregnant of its own accord, suddenly it engendered jealousy. Since that day, the principle of jealousy amongst all the eternal realms and their worlds has been apparent."

"Their chief is blind. Because of his power and his ignorance and his arrogance he said, with his power, “I am god; there is no other but me.”

When he said this, he sinned against all. This speech rose up to incorruptibility. Then there was a voice that came forth from incorruptibility, saying, “You are wrong, Samael,” that is, god of the blind."

"44Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it. 45And because I tell you the truth, ye believe me not. 46Which of you convinceth me of sin? And if I say the truth, why do ye not believe me? 47He that is of God heareth God's words: ye therefore hear them not, because ye are not of God."
