1 Samuel 6:2-4

New International Version - UK

² the Philistines called for the priests and the diviners and said, ‘What shall we do with the ark of the Lord? Tell us how we should send it back to its place.’

³ They answered, ‘If you return the ark of the god of Israel, do not send it back to him without a gift; by all means send a guilt offering to him. Then you will be healed, and you will know why his hand has not been lifted from you.’

⁴ The Philistines asked, ‘What guilt offering should we send to him?’

They replied, ‘Five gold tumours and five gold rats, according to the number of the Philistine rulers, because the same plague has struck both you and your rulers.
