18 On the first day there shall be a holy convocation. You shall not work at your occupations. 19 You shall offer an offering by fire, a burnt offering to the Lord: two young bulls, one ram, and seven male lambs a year old; see that they are without blemish. 20 Their grain offering shall be of choice flour mixed with oil: three-tenths of an ephah shall you offer for a bull, and two-tenths for a ram; 21 one-tenth shall you offer for each of the seven lambs; 22 also one male goat for a sin offering, to make atonement for you. 23 You shall offer these in addition to the burnt offering of the morning, which belongs to the regular burnt offering. 24 In the same way you shall offer daily, for seven days, the food of an offering by fire, a pleasing odor to the Lord; it shall be offered in addition to the regular burnt offering and its drink offering. 25 And on the seventh day you shall have a holy convocation; you shall not work at your occupations.

Matthew Henry's Commentary on Numbers 28:18-25

Commentary on Numbers 28:16-31

(Read Numbers 28:16-31)

By the sacrifices enjoined in this chapter, we are reminded of the continued power of the sacrifice of Christ, and of our continual need to depend thereon. No hurrying employments, or perilous situations, or prosperous circumstances, should cause slackness in our religious exercises; but should rather stir us up to greater diligence in seeking help from, or giving thanks to the Lord. And all is to be accompanied with repentance, faith is the Lord Jesus, and love to him, and to produce true holiness in our conduct towards all men; otherwise God will abhor our most solemn services and abundant devotions. And Christ is able to supply the wants of every day, every week, every month, every year, every ordinance, every case.
