1 Samuel 6:9-12

9Then watch—if it goes up by the way of its own territory to Beth-shemesh, then it was He who inflicted on us this great harm. But if not, then we will know that it was not His hand that struck us; it just happened to us by chance.”

10So the people did so—they took two milk cows and hitched them to the cart, and shut up their calves at home.

11Then they placed the ark of Adonai on the cart together with the box, the golden mice, and the models of their tumors.

12So the cows took the way straight toward Beth-shemesh—they kept along the same highway, lowing as they went, and turned aside neither to the right nor to the left. The lords of the Philistines followed them to the border of Beth-shemesh.
