'Doves' in the Bible
"If his offering is a burnt offering of birds to the LORD, he is to bring turtledoves or young doves.
"If he can't afford a goat, then he is to bring to the LORD for his sin offering two turtledoves or two young doves: one for a sin offering and the other for a burnt offering.
"If he can't afford two turtledoves or two young doves, then he is to bring as his offering a tenth of an ephah of fine flour as a sin offering for what he has committed. He is to put no olive oil or frankincense on it, since it's a sin offering.
If she cannot afford a goat, then two turtledoves or two young doves one for a burnt offering and the other for a sin offering will serve for him to make atonement for her, so that she becomes clean."
On the eighth day, he is to take for himself two turtledoves or two young doves, bring them to the LORD at the entrance to the Tent of Meeting, and give them to the priest.
