A Forgotten Story

I've started working my way through the Old Testament again.  The other day, I read this strange little story about something that happened to Moses between seeing the burning bush and going to tell Pharaoh to let his people go.

At a lodging place on the way, the LORD met Moses and was about to kill him. 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. (At that time she said “bridegroom of blood,” referring to circumcision.) Exodus 4:24-26.

I don't have a nice little homily about this story.  We didn't learn it in Sunday school.  I don't remember ever hearing a sermon about it (and I have heard a lot of sermons).

I really only have two things to say about it:

1. It's not all burning bushes and parting seas.  
2. The Bible has a lot of stories about people interacting with God and some of them are just plain weird.
