To do evil, or to do good - It is very likely that rash promises are here intended; for if a man vow to do an act that is evil, though it would be criminal to keep such an oath or vow, yet he is guilty because he made it, and therefore must offer the trespass-offering. If he neglect to do the good he has vowed, he is guilty, and must in both cases confess his iniquity, and bring his trespass-offering.
Special occasions are mentioned on which sin-offerings are to be made with a particular confession of the offence for which atonement is sought Leviticus 5:5.
Leviticus 5:1
Swearing - Adjuration. The case appears to be that of one who has been put upon his oath as a witness by a magistrate, and fails to utter all he has seen and heard (compare the marginal references. and Proverbs 29:24; Numbers 5:21).
Leviticus 5:2-3
Hid from him - Either through forgetfulness or indifference, so that purification had been neglected. In such a case there had been a guilty negligence, and a sin-offering was required. On the essential connection between impurity and the sin-offering, see Leviticus 12:1.
Leviticus 5:4
Pronouncing - Idly speaking Psalm 106:33. The reference is to an oath to do something uttered in recklessness or passion and forgotten as soon as uttered.
Leviticus 5:6
His trespass offering - Rather, as his forfeit, that is, whatever is due for his offence. The term “trespass-offering” is out of place here, since it has become the current designation for a distinct kind of sin-offering mentioned in the next section (see Leviticus 5:14 note).
A lamb or a kid of the goats - A sheep Leviticus 4:32 or a shaggy she-goat Leviticus 4:23.
Leviticus 5:7-10
See Leviticus 1:14-16; Leviticus 12:8. In the larger offerings of the ox and the sheep, the fat which was burned upon the altar represented, like the burnt-offering, the dedication of the worshipper; in this case, the same meaning was conveyed by one of the birds being treated as a distinct burnt-offering.
Leviticus 5:7
A lamb - One of the flock, either a sheep or a goat.
For his trespass, which he hath committed - As his forfeit for the sin he hath committed.
Leviticus 5:11
tenth part of an ephah i. e. - “the tenth deal;” probably less than half a gallon. See Leviticus 19:36 note. This sin-offering of meal was distinguished from the ordinary מנחה mı̂nchāh Leviticus 2:1 by the absence of oil and frankincense.
