Leviticus 24:12-15

¹²And they kept him shut up, till a decision might be given by the mouth of the Lord.

¹³And the Lord said to Moses,

¹⁴Take the curser outside the tent-circle; and let all in whose hearing the words were said put their hands on his head, and let him be stoned by all the people.

¹⁵And say to the children of Israel, As for any man cursing God, his sin will be on his head.
