Leviticus 1:13-15 English Standard Version Anglicised (ESVUK)
13 but the entrails and the legs he shall wash with water. And the priest shall offer all of it and burn it on the altar; it is a burnt offering, a food offering with a pleasing aroma to the Lord.
14 “If his offering to the Lord is a burnt offering of birds, then he shall bring his offering of turtle-doves or pigeons. 15 And the priest shall bring it to the altar and wring off its head and burn it on the altar. Its blood shall be drained out on the side of the altar.
