Leviticus 5:5-7

Amplified Bible

⁵ So it shall be when a person is guilty in one of these, that he shall confess the sin he has committed. ⁶ He shall bring his guilt offering to the Lord for the 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 ^[a]cannot afford a lamb, then he shall bring two turtledoves or two young pigeons as his guilt offering for his sin to the Lord, one as a sin offering and the other as a burnt offering.
