12 And Moses said to Aaron and to Eleazar and Ithamar, his sons who were still living, Take the rest of the meal offering from the offerings of the Lord made by fire, and take it for your food, without leaven, at the side of the altar, for it is most holy. 13 It is to be for your food in a holy place, because it is your right and your sons' right, from the offerings of the Lord made by fire: for so am I ordered. 14 And the breast which is waved and the leg which is lifted up on high, you are to take as your food in a clean place; you and your sons and your daughters with you: for they are given to you as your right and your sons' right, from the peace-offerings of the children of Israel. 15 Let them take the breast which is waved and the leg which is lifted up on high, with the fat of the burned offering, to be waved for a wave offering before the Lord; and this will be for you and for your sons with you, for a right for ever, as the Lord has given orders.

Commentary on Leviticus 10:12-20

(Read Leviticus 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.
