Zipporah

Zipporah (means little bird) was the Midianite wife of Moses and daughter of Jethro. After 40 years of life in Midian with Zipporah's family, Moses received a message from God that it was time to return to Egypt to free His people.

Along the journey, God came to Moses and sought to kill him. Zipporah took a sharp piece of flint and circumcised her son, casting the boy's foreskin down before Moses. The Lord spared Moses' life.

Zipporah proclaims to Moses, "You are my bridegroom because of bloodshed." She saved her husband's life by the bloodshed of her own child. (Exodus 4)
