If a soul commit a trespass. — The word used here for trespass is not the same which is so rendered in Leviticus 5:19, and from which the noun rendered in this very chapter by trespass offering (Leviticus 5:6-7; Leviticus 5:15-16; Leviticus 5:19), is derived. It literally denotes to cover, then to act covertly, to be faithless, especially in matters of a sacred covenant made either with God (Leviticus 26:40; Numbers 31:16; Deuteronomy 32:51, &c.), or between husband and wife (Numbers 5:12; Numbers 5:27).
And sin through ignorance. — If at the time of its committal he did not know that it was a transgression. (See Leviticus 4:2.)
In the holy things of the Lord. — That is, inadvertently keeping back the things which belong to the sanctuary, and to the service of the Lord, as, for instance, the tithes, the firstfruits, or not consecrating or redeeming his firstborn (Exodus 28:38; Numbers 5:6-8).
A ram without blemish. — For committing any of these transgressions presumptuously, the transgressor incurred the punishment of excision (Numbers 15:30; Hebrews 10:28); but when they were done unawares, he was to bring a ram as a sacrifice. According to the rules which obtained during the second Temple, it must be over thirty-one days in the second year of its age. It was of greater value than the female sheep. The sacrifice for a trespass in holy things, though ignorantly committed, was therefore more costly than for the sin of ignorance mentioned in Leviticus 5:6.
With thy estimation by shekels of silver. — That is, according to the valuation of Moses, to whom this was primarily addressed, the ram is to be so grown up as to be worth several, or at least two shekels. The act of valuing was transferred by Moses to the officiating priests. (See Leviticus 27:8; Leviticus 27:12; Numbers 18:16.) For the shekels of the sanctuary see Exodus 30:13.
