1 Samuel 6:7-9

7And now make a new cart, and take two milch kine, on which there has come no yoke, and tie the kine to the cart, and bring their calves home from them;

8and take the ark of Jehovah, and lay it upon the cart, and the golden jewels, which ye return him as a trespass-offering, put in the coffer by the side thereof; and send it away that it may go.

9And see, if it go up by the way of its own border to Beth-shemesh, it is he who has done us this great evil; if not, then we shall know that it is not his hand that touched us; it was a chance [that] happened to us.
