Leviticus 24:16, 23

And he that blasphemeth the name of Jehovah, he shall surely be put to death; all the congregation shall certainly stone him: as well the sojourner, as the home-born, when he blasphemeth the name of Jehovah, shall be put to death.

And Moses spake to the children of Israel; and they brought forth him that had cursed out of the camp, and stoned him with stones. And the children of Israel did as Jehovah commanded Moses.
