Verses 20-22. - The constant, regular succession of day and night is an emblem of the equally regular supply of royal descendants of David and of Levitical priests, and the countless grains of sand are symbolic of the wonderful increase of their numbers. At first sight the latter part of the promise seems a little unlike a blessing. But we have seen already (on Jeremiah 19:3) that the members of the various branches of the royal family probably occupied the principal offices of the state, and the prophet imagines the future in forms borrowed from the present. A numerous sacerdotal class seemed equally necessary for the due magnificence of the ritual; and we must remember that preternatural fertility of the soil was a standing element of Messianic descriptions. The expressions used are, no doubt, hyperbolical, but the meaning seems clear enough. (Hengstenberg's notion, that the prophet rather indicates the abolition of the royal and sacerdotal distinctions (comp. Exodus 19:6), is surely very far fetched.)

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.Thus saith the Lord, if you can break my covenant of the day,

and my covenant of the night,.... The same with the ordinances of the sun, moon, and stars, Jeremiah 31:35; the original constitution and law of nature, settled from the beginning of the world, and observed ever since, in the constant revolution of day and night; and which was formed into a covenant and promise to Noah, after the deluge, that day and night should not cease, as long as the earth remained, Genesis 8:22; and which has never been, nor can be, broken and made void: so

that there should not be day and night in their season; or turn; continually succeeding each other: this, as it would not be attempted, so could never be effected by any mortals, if it were.
