Numbers 28:9-15

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, Isaiah 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.
