17 and the ram thou dost cut into its pieces, and hast washed its inwards, and its legs, and hast put [them] on its pieces, and on its head;

18 and thou hast made perfume with the whole ram on the altar. It [is] a burnt-offering to Jehovah, a sweet fragrance; a fire-offering it [is] to Jehovah.

19 `And thou hast taken the second ram, and Aaron hath laid -- his sons also -- their hands on the head of the ram,

20 and thou hast slaughtered the ram, and hast taken of its blood, and hast put on the tip of the right ear of Aaron, and on the tip of the right ear of his sons, and on the thumb of their right hand, and on the great toe of their right foot, and hast sprinkled the blood on the altar round about;
