In the book of Exodus, God gives instructions to Moses but then quickly decides to kill Moses.

God is prevented from carrying out the killing.

At best, the text is unclear. At worst, the text as we receive it was corrupted over time. Wait, maybe the worst possibility is that the text was not corrupted but never made any sense--not even on the day it was written. All these explanations are problematic. If the text is unclear, then the question becomes why God (as ultimate author of the Bible) wrote something unclear. If the text was corrupted over time (such as the case of a scribe making an error or omitting cruel lines while copying out text), then the question becomes why God would allow his holy text to be corrupted. If we are receiving the text as originally written and it never made sense--well, that does help anyone make the argument that an infallible God (or Holy Spirit) wrote this sacred text.

I don’t know why God seeks the early death of Moses and don’t understand how any human can interfere after God resolves to do something.

Exodus 4:22-24: The Lord said to Moses, "When you go back to Egypt see that you perform before Pharaoh all the wonders which I have put in your power; but I will harden his heart so that he will not let the people go.”...

On the way, at a place where they stopped for the night, the Lord met Moses and sought to kill him.

God changes his mind about killing Moses due to Zipporah. None of this makes sense to me.

Exodus 4:25-26: But Zipporah took a flint knife, cut off her son’s foreskin, and touched Moses’ feet with it. “Surely you are a bridegroom of blood to me,” she said. So the Lord let him alone.
