1 Samuel 6:2-9

Then they called for their priests and magicians and said, “What should we do with the Ark of the LORD? Tell us how to send it back home!” The priests and magicians answered, “If you send back the Ark of the God of Israel, don’t send it back empty. You must give a penalty offering. If you are then healed, you will know that it was because of the Ark that you had such trouble.” The Philistines asked, “What kind of penalty offering should we send to Israel’s God?” They answered, “Make five gold models of the growths on your skin and five gold models of rats. The number of models must match the number of Philistine kings, because the same sickness has come on you and your kings. Make models of the growths and the rats that are ruining the country, and give honor to Israel’s God. Then maybe he will stop being so hard on you, your gods, and your land. Don’t be stubborn like the king of Egypt and the Egyptians. After God punished them terribly, they let the Israelites leave Egypt. “You must build a new cart and get two cows that have just had calves. These must be cows that have never had yokes on their necks. Hitch the cows to the cart, and take the calves home, away from their mothers. Put the Ark of the LORD on the cart and the gold models for the penalty offering in a box beside the Ark. Then send the cart straight on its way. Watch the cart. If it goes toward Beth Shemesh in Israel’s own land, the LORD has given us this great sickness. But if it doesn’t, we will know that Israel’s God has not punished us. Our sickness just happened by chance.”
