I Samuel 6:8

8 Take the ark of the Lord and put it on the cart, and in a chest beside it put the gold objects you are sending back to him as a guilt offering. Send it on its way,

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