And they said, If ye send away the ark of the God of Israel, send it not empty; but in any wise return him a trespass offering: then ye shall be healed, and it shall be known to you why his hand is not removed from you. Send it not empty - As it appears ye have trespassed against him, send him an offering for this trespass.
Why his hand is not removed - The sense is, If you send him a trespass-offering, and ye be cured, then ye shall know why his judgments have not been taken away from you previously to this offering.
It is a common opinion, says Calmet, among all people, that although the Supreme Being needs nothing of his creatures, yet he requires that they should consecrate to him all that they have; for the same argument that proves his independence, infinitude, and self-sufficiency, proves our dependence, and the obligation we are under to acknowledge him by offering him due marks of our gratitude and submission. Such sentiments were common among all people; and God himself commands his people not to appear before him without an offering, Exodus 23:15 : None shall appear before me empty.
