Leviticus 24:10-16

10One day a man who had an Israelite mother and an Egyptian father came out of his tent and got into a fight with one of the Israelite men.

11During the fight, this son of an Israelite woman blasphemed the Name of the Lord with a curse. So the man was brought to Moses for judgment. His mother was Shelomith, the daughter of Dibri of the tribe of Dan.

12They kept the man in custody until the Lord’s will in the matter should become clear to them.

13Then the Lord said to Moses,

14“Take the blasphemer outside the camp, and tell all those who heard the curse to lay their hands on his head. Then let the entire community stone him to death.

15Say to the people of Israel: Those who curse their God will be punished for their sin.

16Anyone who blasphemes the Name of the Lord must be stoned to death by the whole community of Israel. Any native-born Israelite or foreigner among you who blasphemes the Name of the Lord must be put to death.
