The ordinances of heaven and earth - i. e., the whole order of nature Nature is not more firmly established than God's purposes in grace.

Thus saith the Lord,.... In answer to the above calumny:

if my covenant be not with day and night; that is, if it should not stand; if it should be broken; or there should be no longer a succession of day and night:

and if I have not appointed the ordinances of heaven and earth; concerning the course of the sun, moon, and stars, and the influence of the heavenly bodies; and concerning the fruits of the earth, the seasons of the year, seedtime and harvest, summer and winter; if these are not settled and fixed, and do not appear according to appointment and promise.

Thus saith the LORD; If my covenant be not with day and night, and if I have not appointed the ordinances of heaven and earth;

25. (Jer 31:35, 36; Ge 8:22; Ps 74:16, 17). I who have established the laws of nature am the same God who has made a covenant with the Church.

33:14-26 To crown the blessings God has in store, here is a promise of the Messiah. He imparts righteousness to his church, for he is made of God to us righteousness; and believers are made the righteousness of God in him. Christ is our Lord God, our righteousness, our sanctification, and our redemption. His kingdom is an everlasting kingdom. But in this world prosperity and adversity succeed each other, as light and darkness, day and night. The covenant of priesthood shall be secured. And all true believers are a holy priesthood, a royal priesthood, they offer up spiritual sacrifices, acceptable to God; themselves, in the first place, as living sacrifices. The promises of that covenant shall have full accomplishment in the gospel Israel. In Ga 6:16, all that walk according to the gospel rule, are made to be the Israel of God, on whom shall be peace and mercy. Let us not despise the families which were of old the chosen people of God, though for a time they seem to be cast off.
