In every dispute that your fellow Israelis who live in the cities want you to settle, you must warn them to not sin against Yahweh by telling lies during the trial. If you do not warn them, God will punish both you and your fellow Israelis. If you warn them, you will not be sinning. You must warn them whether someone has accused them of murdering someone, or of disobeying some other law or command or decree of Yahweh.
