1 Samuel 6:10-12

10Then the men did so, and took two milch cows and hitched them to the cart, and shut up their calves at home. 11They put the ark of the Lord on the cart, and the box with the golden mice and the likenesses of their tumors. 12And the cows took the straight way in the 1direction of 2Beth-shemesh; they went along 3the highway, lowing as they went, and did not turn aside to the right or to the left. And the lords of the Philistines followed them to the border of Beth-shemesh.
