but its entrails and its legs he shall wash with water. And the priest shall burn all of it on the altar, as a burnt offering, a food offering with a pleasing aroma to the LORD.

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.

He shall tear it open by its wings, but shall not sever it completely. And the priest shall burn it on the altar, on the wood that is on the fire. It is a burnt offering, a food offering with a pleasing aroma to the LORD.
