Matthew Poole and continuators on Jeremiah 33:20

20 Thus saith the LORD If you can break my covenant of the day, and my covenant of the night , and that there should not be day, and night in their season.

By the Covenant of day and night here is meant the same with the Ordinances mentioned, chap. 31.35. Gods Law established in the course of natural causes, by vertue of which the day, and night orderly succeed one another. These verses are but a further confirmation of what was said before, and the sense of them no more then this. That the succession [illegible: 1 letter]f the Gospel Ministry in the Church of God to abide for ever, should be as certain as the succession of darkness and light, God had established the latter in a necessary course of natural causes, and he would by his Providence take care for the other, that the effect should be every whit as certain. Though the second causes are widely different, yet God who is the first cause of both is the same, and would as certainly bring the one to pass as the other.
