Exodus 18:2

Jethro, Moses' father-in-law, received Zipporah, Moses' wife, after he had sent her away,

Moses was content to dwell with the man. He gave Moses Zipporah, his daughter.

Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, "Surely you are a bridegroom of blood to me."

Then Jethro, Moses' father in law, took Zipporah, Moses' wife, after he had sent her back,

Moses was content to dwell with the man. He gave Moses Zipporah, his daughter.

Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, "Surely you are a bridegroom of blood to me."

So Moses listened to the voice of his father-in-law, and did all that he had said.

Moses fled at this saying, and became a stranger in the land of Midian, where he became the father of two sons.
