C. F. Keil and Franz Delitzsch on Leviticus 5:5-6

Lev 5:5-6

If any one therefore (the three cases enumerated are comprehended under the one expression כי והיה, for the purpose of introducing the apodosis) had contracted guilt with reference to one of these (the things named in Lev 5:1-4), and confessed in what he had sinned, he was to offer as his guilt (trespass) to the Lord, for the sin which he had sinned, a female from the flock-for a sin-offering, that the priest might make atonement for him on account of his sin. אשׁם (Lev 5:6) does not mean either guilt-offering or debitum (Knobel), but culpa, delictum, reatus, as in Lev 5:7 : “as his guilt,” i.e., for the expiation of his guilt, which he had brought upon himself.
