and take the ark of Yahweh, and lay it on the cart; and put the jewels of gold, which you return him for a trespass-offering, in a coffer by the side of it; and send it away, that it may go.
Yahweh had reduced the fertility of the crops of the Philistines as well as afflicting the people and their gods (1 Samuel 6:5). The Philistines remembered that this is what Yahweh had done to the Egyptians earlier (1 Samuel 6:6). The priests counseled the people not to harden their hearts as Pharaoh had done. Hardening the heart only brings divine retribution (cf. Joshua 7:19).
