Leviticus 24:16, 23

Whoever blasphemes the name of the LORD shall surely be put to death. All the congregation shall stone him. The sojourner as well as the native, when he blasphemes the Name, shall be put to death.

So Moses spoke to the people of Israel, and they brought out of the camp the one who had cursed and stoned him with stones. Thus the people of Israel did as the LORD commanded Moses.
