2 Kings 12:16 - Joseph Benson’s Commentary on the Old and New Testaments

The trespass-money and sin-money, &c. “Besides the money paid to the priests for trespasses committed in holy things it is thought that persons living at a distance sent money to the priests to purchase trespass- offerings and sin-offerings, and sacrifice them in their names: and, as they commonly sent more than the sacrifices cost, the surplus became a perquisite, under the name of trespass-money and sin-money.” Scott.
