Exodus 2:13, 21-22

The next day he went out and saw two Hebrews fighting. He asked the one in the wrong, “Why are you hitting your fellow Hebrew?”

Moses agreed to stay with the man, who gave his daughter Zipporah to Moses in marriage. Zipporah gave birth to a son, and Moses named him Gershom, saying, “I have become a foreigner in a foreign land.”
