Proverbs 19:17 - Joseph Benson’s Commentary on the Old and New Testaments

He that hath pity on the poor And relieves their necessities; lendeth unto the Lord Doth not empoverish, but enrich himself: for the Lord takes what is done to them as done to himself, because it is done to those whom he has appointed in his own stead to be his receivers, and whom he hath, in a peculiar manner, commended to the care and charity of all other men. He therefore will not fail to make a full compensation; he will return the benefit done to others, with large interest and increase of blessings, upon the beneficent man and his posterity.
