I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul. Leviticus 17:11And if any soul sin through ignorance, then he shall bring a she goat of the first year for a sin offering. And the priest shall make an atonement for the soul that sinneth ignorantly, when he sinneth by ignorance before the LORD, to make an atonement for him; and it shall be forgiven him. Numbers 15:27-28
And one kid of the goats for a sin offering: to make an atonement for you. Numbers 29:5
For it is not possible that the blood of bulls and of goats should take away sins. Hebrews 10:4And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins. Hebrews 10:11
