Leviticus 5:18

18 you must bring a flawless ram from the flock, at the standard value, as a compensation offering to the priest. The priest will make reconciliation for you for the unintentional fault that you committed, even though you didn't realize it, and you will be forgiven.

Leviticus 5:18 Meaning and Commentary

Leviticus 5:18

And he shall bring a ram without blemish out of the flock,
&c.] (See Gill on Leviticus 5:15)

with thy estimation for a trespass [offering] to the priest;
along with the offering was to be brought an estimate of whatsoever damage had been done through the breach of any of the commands of God, where damage could take place, that so recompense be made as before directed; or else the ram brought was to be valued, and examined whether it was worth two shekels of silver, as before explained, (See Gill on Leviticus 5:15) but no fifth was required as in the former cases:

and the priest shall make atonement for him concerning his
ignorance wherein he erred, and wist [it] not, and it shall be
forgiven him; (See Gill on Leviticus 5:10) this is what the Jews call "Asham Talui", doubtful trespass offering.

Leviticus 5:18 In-Context

16 You will make amends for the way you have sinned against the holy thing: you will add one-fifth to its value and give it to the priest. Then the priest will make reconciliation for you with the ram for the compensation offering, and you will be forgiven.

17 If you sin by breaking any of the LORD's commands, but without realizing it, doing something that shouldn't be done, and then become guilty and liable to punishment,

18 you must bring a flawless ram from the flock, at the standard value, as a compensation offering to the priest. The priest will make reconciliation for you for the unintentional fault that you committed, even though you didn't realize it, and you will be forgiven.

19 It is a compensation offering. You have definitely become guilty before the LORD.
