Leviticus Chapter 4 NASB
25 Then the priest is to take some of the blood of the sin offering with his finger and put it on the horns of the altar of burnt offering; and the rest of its blood he shall pour out at the base of the altar of burnt offering. 26 All its fat he shall offer up in smoke on the altar as in the case of the fat of the sacrifice of peace offerings. Thus the priest shall make atonement for him in regard to his sin, and he will be forgiven.
Leviticus Chapter 5 NASB
1‘Now if a person sins after he hears a public adjuration to testify when he is a witness, whether he has seen or otherwise known, if he does not tell it, then he will bear his guilt. 2 Or if a person touches any unclean thing, whether a carcass of an unclean beast or the carcass of unclean cattle or a carcass of unclean swarming things, though it is hidden from him and he is unclean, then he will be guilty. 3 Or if he touches human uncleanness, of whatever sort his uncleanness may be with which he becomes unclean, and it is hidden from him, and then he comes to know it, he will be guilty. 4 Or if a person swears thoughtlessly with his lips to do evil or to do good, in whatever matter a man may speak thoughtlessly with an oath, and it is hidden from him, and then he comes to know it, he will be guilty in one of these. 5 So it shall be when he becomes guilty in one of these, that he shall confess that in which he has sinned.
6 He shall also bring his guilt offering to the Lord for his sin which he has committed, a female from the flock, a lamb or a goat as a sin offering. So the priest shall make atonement on his behalf for his sin.
7‘But if he cannot afford a lamb, then he shall bring to the Lord his guilt offering for that in which he has sinned, two turtledoves or two young pigeons, one for a sin offering and the other for a burnt offering. He shall bring them to the priest, who shall offer first that which is for the sin offering and shall nip its head at the front of its neck, but he shall not sever it.
Leviticus Chapter 6:1-12 NASB
1 Then the Lord spoke to Moses, saying, 2“When a person sins and acts unfaithfully against the Lord, and deceives his companion in regard to a deposit or a security entrusted to him, or through robbery, or if he has extorted from his companion, 3 or has found what was lost and lied about it and sworn falsely, so that he sins in regard to any one of the things a man may do; 4 then it shall be, when he sins and becomes guilty, that he shall restore what he took by robbery or what he got by extortion, or the deposit which was entrusted to him or the lost thing which he found,
5 or anything about which he swore falsely; he shall make restitution for it in full and add to it one-fifth more. He shall give it to the one to whom it belongs on the day he presents his guilt offering. 6 Then he shall bring to the priest his guilt offering to the Lord, a ram without defect from the flock, according to your valuation, for a guilt offering, 7 and the priest shall make atonement for him before the Lord, and he will be forgiven for any one of the things which he may have done to incur guilt.” 8 Then the Lord spoke to Moses, saying, 9“Command Aaron and his sons, saying, ‘This is the law for the burnt offering: the burnt offering itself shall remain on the hearth on the altar all night until the morning, and the fire on the altar is to be kept burning on it. 10 The priest is to put on his linen robe, and he shall put on undergarments next to his flesh; and he shall take up the ashes to which the fire reduces the burnt offering on the altar and place them beside the altar. 11 Then he shall take off his garments and put on other garments, and carry the ashes outside the camp to a clean place. 12 The fire on the altar shall be kept burning on it. It shall not go out, but the priest shall burn wood on it every morning; and he shall lay out the burnt offering on it, and offer up in smoke the fat portions of the peace offerings on it. 1
