When I originally pondered OP's scriptures in my own studies, I thought perhaps Jesus is God in the scriptures but with an alternative understanding than what is generally taught.
Duet 32:8,9 when Most High separated sons of man, and Israel was Jehovah/Yahweh's inheritance. Seems to show a seperation. How does the almighty 'inherit'??
Ps 82:1 Jehovah/Yahweh (perhaps judging how the others were handling their inheritance since he got Israel?)
Ex 32:30 God or Jehovah (or maybe the 'real' one) saying he will send his angel before them, who has HIS NAME, and they better obey him because he is a strict bad @## (would explain differences between dealings and appearingly super strict and unforgiving nature if it was this other entity he warned them about)
But then when they were wandering for 40 years, compare Ex 32:30 with what is said in Isaiah and Stephen before he was martyred at Act 17:42 and 43. - were those commands Stephen is referencing from this angel that was sent before them, or were the sacrifices and commands man made? Stephen is quoting Isaiah 1:11-13 which makes Yahweh/Jehovah seem to say he never commanded sacrifices. Is 1:11-13 sounds like something Jesus would say and sounds different from the cold orders in previous scriptures.
Jeremiah claims all their sacrifices were ordered or for the queen of the heavens....Jer 44:19.
So, if almighty is Yahweh/Jehovah, Jesus or his son or a son could have his name/authority and have been the one dealing with Israel. Or a strict angel after they rebelled, maybe the angel who killed the firstborns was used to lead them then.
Another interesting scripture. Have you ever heard of Satan or a supposed bad guy having been given people to lead? Is 14:10-20, there was somebody in those scriptures who was conquering the world, disabling nations, and killed his own people. Who was doing that?
