Leviticus 14:30-32 New American Standard Bible (NASB)

30. He shall then offer one of the turtledoves or young pigeons, which are within his means.

31. He shall offer what he can afford, the one for a sin offering and the other for a burnt offering, together with the grain offering. So the priest shall make atonement before the Lord on behalf of the one to be cleansed.

32. This is the law for him in whom there is an infection of leprosy, whose means are limited for his cleansing."
