17If anyone sins, and does any of the things which Yahweh has commanded not to be done; though he didn`t know it, yet he is guilty, and shall bear his iniquity. 18He shall bring a ram without blemish out of the flock, according to your estimation, for a trespass-offering, to the priest; and the priest shall make atonement for him concerning the thing in which he erred unwittingly and didn`t know it, and he shall be forgiven.
