1 Samuel 6:4-13

And they said, “What is the guilt offering that we shall return to him?” They answered, “Five golden tumors and five golden mice, according to the number of the lords of the Philistines, for the same plague was on all of you and on your lords. So you must make images of your tumors and images of your mice that ravage the land, and give glory to the God of Israel. Perhaps he will lighten his hand from off you and your gods and your land. Why should you harden your hearts as the Egyptians and Pharaoh hardened their hearts? After he had dealt severely with them, did they not send the people away, and they departed? Now then, take and prepare a new cart and two milk cows on which there has never come a yoke, and yoke the cows to the cart, but take their calves home, away from them. And take the ark of the LORD and place it on the cart and put in a box at its side the figures of gold, which you are returning to him as a guilt offering. Then send it off and let it go its way and watch. If it goes up on the way to its own land, to Beth-shemesh, then it is he who has done us this great harm, but if not, then we shall know that it is not his hand that struck us; it happened to us by coincidence.” The men did so, and took two milk cows and yoked them to the cart and shut up their calves at home. And they put the ark of the LORD on the cart and the box with the golden mice and the images of their tumors. And the cows went straight in the direction of Beth-shemesh along one highway, lowing as they went. They turned neither to the right nor to the left, and the lords of the Philistines went after them as far as the border of Beth-shemesh. Now the people of Beth-shemesh were reaping their wheat harvest in the valley. And when they lifted up their eyes and saw the ark, they rejoiced to see it.
