Leviticus 14:20-22

New Century Version

²⁰ and he will offer the burnt offering and grain offering on the altar. In this way he will make that person clean so he can belong to the Lord again.

²¹ “But if the person is poor and unable to afford these offerings, he must take one male lamb for a penalty offering. It will be presented to the Lord to make him clean so he can belong to the Lord again. The person must also take two quarts of fine flour mixed with oil for a grain offering. He must also take two-thirds of a pint of olive oil ²² and two doves or two young pigeons, which he can afford. One bird is for a sin offering and the other for a whole burnt offering.
