Leviticus 24:16, 23

Anyone 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.

After Moses gave all these instructions to the Israelites, they took the blasphemer outside the camp and stoned him to death. The Israelites did just as the LORD had commanded Moses.
