Verse 15. A trespass - Against the Lord and his priests. Through ignorance - For if a man did it knowingly, he was to be cut off, Num. xv, 30. In the holy things - In things consecrated to God, and to holy uses; such as tithes and first-fruits, or any things due, or devoted to God, which possibly a man might either with-hold, or employ to some common use. A ram - A more chargeable sacrifice than the former, as the sin of sacrilege was greater. With thy estimation - As thou shalt esteem or rate it, thou, O priest; and at present, thou, O Moses, for he as yet performed the priest's part. And this was an additional charge and punishment to him; besides the ram, he was to pay for the holy thing which he had with-held or abused, so many shekels of silver as the priest should esteem proportionable to it.
Verse 17. The former law concerns the alienation of holy things from sacred to common use; this may concern other miscarriages about holy things, and holy duties, as may be gathered from ver. 19, where this is said to be a trespass against the Lord, not in a general sense, for so every sin was; but in a proper and peculiar sense.
