The way to read and comprehend the books of the bible is to approach them with historical method, the same as you'd approach any other ancient document. In each case what, where, when, who, why? What corroboration exists in other texts or in archaeology for what is reported? If the document's argument is accepted, who benefits?
And so on.
When we first meet the bible God in archaeology, [he]'s a tribal God in the Canaanite pantheon and it appears that as is usual [he] has a consort, Asherah. When we first meet the bible God in the bible, that's no longer the case, but [he]'s still just one of many Canaanite gods. That's why the commandment says you shall not have any gods BEFORE him, and doesn't say, Ain't no other gods. And there's ─
Judges 11;24 Will you not possess what Chemosh your god gives you to possess? And all that the LORD our God has dispossessed before us, we will possess.
and
Psalms 82:1 God has taken his place in the divine council;
in the midst of the gods he holds judgment.
Psalms 86:8 There is none like thee among the gods, O Lord,
nor are there any works like thine.
Psalms 95:3 For the Lord is a great god,
and a great King above all gods.
As you know, the assertion that your god is better than their god is called "henotheism".
Not till after the Babylonian capitivity does God get to be the only god.
Not till Christianity does [he] become two gods, on the one hand remaining the Jewish God and on the other becoming the distinct Christian God, who, thanks in no small part to Paul, no long requires the Jewish covenant of circumcision to be observed.
Not until the 4th century, when the Trinity doctrine is adopted, does the Christian god become triune (notwithstanding that in the NT the Jesus of Paul, the Jesus of Mark, the Jesus of Matthew, the Jesus of Luke and the Jesus of John each expressly deny they're God, and would have looked silly had they not, praying "If it be my will, let this cup pass from me" for instance).
And now we have the Jesus of the Mormons, the Jesus of the Rastafarians, and the Jesuses of the very many (tens of thousands, the net suggests) distinct Christian sects.
The way God is the same yesterday today and tomorrow is in the way [he] keeps changing.
