Exodus 22:8-9

8But if you do not find the robber, you must take your neighbour to stand in front of the judges. They must decide if your neighbour has taken your things for himself.

9Perhaps two people both say that something belongs to them. They may argue about a cow, a donkey, a sheep, some clothes or anything else that they have lost. Then both of them must go to stand in front of the judges. The judges will decide which of them is guilty. The guilty person must pay back twice the value of the thing to the other person.
