12 Then Moses spoke to Aaron , and to his surviving sons , Eleazar and Ithamar , " Take the grain offering that is left over from the Lord'S offerings by fire and eat it unleavened beside the altar , for it is most holy . 13 "You shall eat it, moreover, in a holy place , because it is your due and your sons' due out of the Lord'S offerings by fire ; for thus I have been commanded . 14 " The breast of the wave offering , however, and the thigh of the offering you may eat in a clean place , you and your sons and your daughters with you; for they have been given as your due and your sons' due out of the sacrifices of the peace offerings of the sons of Israel . 15 " The thigh offered by lifting up and the breast offered by waving they shall bring along with the offerings by fire of the portions of fat , to present as a wave offering before the Lord ; so it shall be a thing perpetually due you and your sons with you, just as the Lord has commanded ."

Matthew Henry's Commentary on Leviticus 10:12-15

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.
