(15) The heave shoulder and the wave breast shall they bring.--That is, the offerers who devoted these portions of the peace offering to the Lord, are to bring them to the officiating priests. (See Leviticus 7:29-30.)

10:12-20 Afflictions should rather quicken us to our duty, than take us from it. But our unfitness for duty, when it is natural and not sinful, will have great allowances made for it; God will have mercy, and not sacrifice. Let us profit by the solemn warning this history conveys. When professing worshippers come with zeal without knowledge, carnal affections, earthly, light, vain, trifling thoughts, the devices of will-worship, instead of the offering of soul and spirit; then the incense is kindled by a flame which never came down from heaven, which the Spirit of a holy God never sent within their hearts.The heave shoulder and wave breast shall they bring,.... Not the priests, but the owners to the priests, Leviticus 7:29,

with the offerings made by fire of the fat: upon the inwards, kidneys, and caul of the liver, which was all burnt:

to wave it for a wave offering before the Lord, the shoulder was lifted up, and the breast waved to and fro before the Lord of the whole earth, and towards the several parts of it, to show and own his right to all they had, and then they were given to the priests as a token of it:

and it shall be thine, and thy sons with thee; both the shoulder and the breast:

by a statute for ever, to be observed as long as the ceremonial law and Levitical priesthood lasted, even to the end of the Jewish age and economy, and the coming of the Messiah:

as the Lord hath commanded; Leviticus 7:33.
