Zipporah

From Conservapedia

Zipporah was the daughter of a priest of Midian. Her father's name was Jethro, a name that is repeated nine times in the Bible in the book of Exodus although the first time he is mentioned he is called Reuel (Exodus 2:18), a title that is never used again. Zipporah was the wife of Moses (Exodus 2:21) and they had two sons together, Gershom (Exodus 2:22) and Eliezer (Exodus 18:4).

It appears Zipporah once saved Moses' life by cutting off the foreskin of their son (Exodus 4:25-26), a requirement of God's covenant with the Jewish people. The text does not explain further, although it could be that Moses had avoided circumcising his son. Zipporah's reference to

"A bloody husband [thou art], because of the circumcision"

could imply that she did not approve of the procedure.
