To me it's looking more and more like there's more than one god throughout the Old Testament. He gets confused with angels and demons all the time, and "Elohim" seems to be a catch-all name for any kind of deity, even ghosts.

Compare the way the god of Genesis 2-3 acts with the one in Genesis 4. The former is extremely vengeful and gives very harsh curses for the offense of eating fruit from the wrong tree, as if the knowledge itself wasn't already enough. And then he fears that if man lives forever he would become "like one of us", so apparently this is a polytheistic god, who shows little concern for his creation now that it hasn't worked out the way he wanted it to, meaning he also makes mistakes. But then the god of chapter 4 puts marks on murderers so no one will take revenge on them, even though he warned them not to murder or do wrong. Cain does accuse him of cursing him, but he himself never actually says he gave the curse (and scribes probably edited it to make Cain say so). Then in chapter 6 we're back to the first god who forever resents his creatures for disobeying him, and apparently doesn't have the all-encompassing power to make it go his way. And obviously almost all of the New Testament is the chapter 4 god, and it occasionally mentions a "god/archon of this world" as an enemy.
