The verb “commit" (m‛l) normally indicates that one has violated their legal obligation; they have acted unfaithfully or treacherously. The term often occurs in the context of breaking covenantal relationships, such as the relationship between the Lord and the Israelites (Leviticus 26:40; Joshua 22:16; Joshua 22:31; Ezekiel 14:13; Ezekiel 17:20; Ezekiel 20:27; Ezekiel 39:23), and husband and wife (Numbers 5:12). This suggests to the reader that these sins are not petty crimes but the violation of holy things. However, in light of the passage as a whole, the reader must bear in mind that this action does not suggest a premeditated sin. The adverbial phrase, “sins unintentionally” sheds light on the nature of the sin in question. The specific offence, however, is left unstated.
15 “If anyone commits a breach of faith and sins unintentionally in any of the holy things of the LORD, he shall bring to the LORD as his compensation, a ram without blemish out of the flock, valued in silver shekels, according to the shekel of the sanctuary, for a guilt offering.
