28:1-8 God saw fit now to repeat the law of sacrifices. This was a new generation of men; and they were concerned to keep their peace with God when at war with their enemies. The daily sacrifice is called a continual burnt-offering; when we are bid to pray always, at least every morning and evening we should offer up solemn prayers and praises to God. Nothing is added here but that the wine poured out in the drink-offering is to be strong wine, to teach us to serve God with the best we have. It was a figure of the blood of Christ, the memorial of which is still left to the church in wine; and of the blood of the martyrs, which was poured out as a drink-offering on the sacrifice and service of our faith, Php 2:17.

28:9-15 Every sabbath day, beside the two lambs offered for the daily burnt-offering, there must be two more offered. This teaches us to double our devotions on sabbath days, for so the duty of the day requires. The sabbath rest is to be observed, in order more closely to apply ourselves to the sabbath work, which ought to fill up the sabbath time. The offerings in the new moons showed thankfulness for the renewing of earthly blessings: when we rejoice in the gifts of providence, we must make the sacrifice of Christ, that great gift of special grace, the fountain and spring-head of our joy. And the worship performed in the new moons is made typical of gospel solemnities, Isa 66:23. As the moon borrows light from the sun, and is renewed by its influences; so the church borrows her light from Jesus Christ, who is the Sun of righteousness, renewing the state of the church, especially under the gospel.

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.
