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. 16 And Moses was looking for the goat of the sin-offering, but it was burned; and he was angry with Eleazar and Ithamar, the sons of Aaron, who were still living, saying, 17 Why did you not make a meal of the sin-offering in the holy place? For it is most holy and he has given it to you, so that the sin of the people may be put on it, to take away their sin before the Lord. 18 See, its blood was not taken into the holy place: certainly it was right for you to have taken it as food in the holy place, as I gave orders. 19 And Aaron said to Moses, You have seen that today they have made their sin-offering and their burned offering before the Lord, and such things as these have come on me. If I had taken the sin-offering as food today, would it have been pleasing to the Lord? 20 And after hearing this, Moses was no longer angry.

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.
