Leviticus 5:18
And he shall bring a ram without blemish out of the flock, with thy estimation, for a trespass offering, unto the priest: and the priest shall make an atonement for him concerning his ignorance wherein he erred and wist it not, and it shall be forgiven him.
And he shall bring a ram without blemish out of the flock,.... 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.
