'Cursing' in the Bible

Every man cursing his father or his mother is certainly to be put to death; because of his curse on his father or his mother, his blood will be on him.

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

And Moses said these words to the children of Israel, and they took the man who had been cursing outside the tent-circle and had him stoned. The children of Israel did as the Lord gave orders to Moses.
