Leviticus 5:18

18 He must bring the priest a male sheep from the flock, one that has nothing wrong with it and that is worth the correct amount. It will be a penalty offering. Though the person sinned without knowing it, with this offering the priest will remove the sin so the person will belong to the Lord, and the Lord will forgive him.

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 That person must pay for the sin he did against the holy thing, adding one-fifth to its value. Then he must give it all to the priest. In this way the priest will remove the person's sin so he will belong to the Lord, by using the male sheep as the penalty offering. And the Lord will forgive the person.

17 "If a person sins and does something the Lord has commanded not to be done, even if he does not know it, he is still guilty. He is responsible for his sin.

18 He must bring the priest a male sheep from the flock, one that has nothing wrong with it and that is worth the correct amount. It will be a penalty offering. Though the person sinned without knowing it, with this offering the priest will remove the sin so the person will belong to the Lord, and the Lord will forgive him.

19 The person is guilty of doing wrong, so he must give the penalty offering to the Lord."
