1 Samuel 6:8-10

Amplified Bible

⁸ Then take the ark of the Lord and put it on the cart; and put the articles of gold which you are returning to Him as a guilt offering in a box beside it. Then send it away [without a driver]. ⁹ But watch, ^[a]if it goes up by the way of its own territory to ^[b]Beth-shemesh, then [you will know that] He has done us this great evil. But if not, then we will know that it was not His hand that struck us; this disaster happened to us by chance.”

¹⁰ And the men did so, and took two milk cows and hitched them to the cart, and corralled their calves at home.
