Leviticus 24:10-16

10Now the son of an Israelite mother and an Egyptian father went out among the Israelites, and a fight broke out in the camp between him and an Israelite. 11The son of the Israelite woman blasphemed the Name with a curse. So they brought him to Moses. (His mother’s name was Shelomith daughter of Dibri, of the tribe of Dan.)

12They placed him in custody until the will of the LORD should be made clear to them.

13Then the LORD said to Moses, 14“Take the blasphemer1 outside the camp, and have all who heard him lay their hands on his head; then have the whole assembly stone him.

15And you are to tell the Israelites, ‘If anyone curses his God, he shall bear the consequences of his sin. 16Whoever blasphemes the name of the LORD must surely be put to death; the whole assembly must surely stone him, whether he is a foreign resident or native; if he blasphemes the Name, he must be put to death.
