1 Samuel 6:1-3

1After the ark of Adonai had been in the country of the Philistines seven months,

2the Philistines summoned the priests and the diviners saying, “What should we do with the ark of Adonai? Tell us how we should send it back to its place.”

3So they said, “If you are going to send the ark of the God of Israel back, do not send it empty. For you must surely return it with a guilt offering. Then you will be healed and it will be revealed to you why His hand has not been removed from you.”
