1 Samuel 14:40

40Then he said to all the Israelites, “14:40 To identify the guilty party, Saul decided to have lots cast, which was a common and accepted means of finding God’s will. It may be that the Urim and Thummim that were kept in the priest’s breastpiece were used for this purpose (Ex 28:30). Saul chose to narrow the search by first separating Jonathan and himself from the rest of the people, only to discover (v 41) that the people were in fact innocent.You shall be on one side; I and my son Jonathan will be on the other side.” The people said to Saul, “Do what seems good to you.”
