Leviticus 5:18

18 You must bring the priest a ram that has no defects from the flock or its value in money for a guilt offering. The priest will make peace with the LORD for the wrong you did unintentionally (although you didn't know what you did), 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 Pay for whatever holy things you used plus one-fifth more. Give it to the priest. So the priest will use the ram sacrificed for the guilt offering to make peace with the LORD for what you did wrong, and you will be forgiven.

17 "If any of you do wrong--even one thing forbidden by any of the LORD's commands, but you didn't know it--when you realize your guilt, you must be punished.

18 You must bring the priest a ram that has no defects from the flock or its value in money for a guilt offering. The priest will make peace with the LORD for the wrong you did unintentionally (although you didn't know what you did), and you will be forgiven.

19 It is a guilt offering because you are certainly guilty as far as the LORD is concerned."
