Leviticus 1:14-17 - From The Birds
14 "If his offering is a burnt offering of birds to the LORD, he is to bring turtledoves or young doves. 15 The priest is to bring it to the altar to offer it up in smoke. He is to decapitate it and drain its blood on the side of the altar, 16 and then he is to eviscerate it and throw the viscera and the feathers to the east side of the altar, where the fatty ashes are located. 17 He is then to tear it open by its wings, but not divide it completely into two parts. The priest is then to offer all of it on the wood over the fire as a burnt offering by fire, an aroma pleasing to the LORD."
