Leviticus 24:16, 23

Moreover, the one who blasphemes the name of the LORD shall surely be put to death; all the congregation shall certainly stone him. The alien as well as the native, when he blasphemes the Name, shall be put to death.

Then Moses spoke to the sons of Israel, and they brought the one who had cursed outside the camp and stoned him with stones. Thus the sons of Israel did, just as the LORD had commanded Moses.
