1 Samuel 6:8-11

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.” The Philistines did what the priests and magicians said. They took two cows that had just had calves and hitched them to the cart, but they kept their calves at home. They put the Ark of the LORD and the box with the gold rats and models of growths on the cart.
