Today’s chapter features the first half of a conversation with God that will turn Moses around and send him back to Egypt. It features a miraculous flaming bush that burns for far longer than a bush has any right to, and which emits God’s voice. It features Moses’ commission to bring the people of Israel back to the land that is their birthright. It features God’s holiness and compassion in equal measure. And, famously, it features God formally giving his name, the tetragrammaton YHWH. But the event raises a question: why the crud does Moses need to be told God’s name?
Finally, Abraham is officially Abraham! Now I can stop feeling weird when I refer to him by the name by which he is most widely known, but which he has not technically been given yet!
So, God has explicitly promised Abraham an heir who is his son by birth. But Sarah has been unable to conceive and is well past child-bearing age. Where is this heir going to come from? Sarah has an idea: God said the heir would come from Abraham, but he didn’t say it had to come from Sarah. Thus, she’ll give her maid Hagar to Abraham, and Hagar and Abraham will have the child. Problem solved, right? No. There are complications.
