OK, you believe parts of the Bible.
Prophets warned Israel not to worship false gods before the exile. God tells Israel through Isaiah that He is the only God and there are no others.
Those who are true to the one true God, YHWH, believe that imo.
YHWH does not have anyone sacrifice anything to Azazel.
Deuteronomy 4:35,39 — Unto thee it was shown, that thou mightest know that the LORD he is God;
there is none else beside him. (39) Know therefore this day, and consider it in thine heart, that the LORD he is God in heaven above, and upon the earth beneath: there is none else.
Deuteronomy32:39 — See now that I, even I, am he, and
there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand.
Since Deuteronomy clearly says that YHWH is the only God, it sees that it would be common sense to not call the sons of God, real gods. Angels would be more appropriate. Where is there a distinction drawn between sons of God in heaven and angels?
OK but that is rather finicky when Israel included Judah and Benjamine initially.
Through the time of the Judges there were lapses in the monotheism of Israel and God punished and brought the people back to Him for a time. Saul, David and Solomon saw mainly monotheism. But going after idols and not sticking to monotheism was not far from the surface. That seems to be what the Bible says imo.
If Israel had been anything other than monotheistic then YHWH would not have used David and Solomon as He did to establish Israel and YHWH worship solidly around the Temple worship. But as I said, idolatry was close to the surface and reared it's ugly head more and more even though God warned the people and Kings through the prophets. Only a handful of the Kings of either Kingdom did as God wanted and tried to stop worship of other gods.
But these other gods were not true gods according to YHWH, but of course they existed just as Krishna and Ganeesha exist today.
