Jeremiah 33:20

20 The Lord saith these things, If my covenant with the day, and my covenant with the night, may be made void, that the day and the night be not in his time; (The Lord saith these things, Only if my covenant with the day, and my covenant with the night, could ever be made void, so that the day and the night be not at their proper time;)

Jeremiah 33:20 Meaning and Commentary

Jeremiah 33:20

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 Jeremiah 31:36 ) ; 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.

Jeremiah 33:20 In-Context

18 and of [the] priests and deacons, a man shall not perish from (before) my face, that shall offer burnt sacrifices, and burn sacrifices, and slay sacrifice(s), in all days. (and a priest of the Levites shall always offer the burnt sacrifices to me, and shall burn the sacrifices, and shall kill the sacrifices.)

19 And the word of the Lord was made to Jeremy, and said,

20 The Lord saith these things, If my covenant with the day, and my covenant with the night, may be made void, that the day and the night be not in his time; (The Lord saith these things, Only if my covenant with the day, and my covenant with the night, could ever be made void, so that the day and the night be not at their proper time;)

21 and my covenant with David, my servant, may be voided, that of him be no son, that shall reign in his throne, and no deacons, and priests, my ministers; (then could my covenant with my servant David be made void, so that there would no longer be any of his sons, who shall reign on his throne, and no longer any priests of the Levites, who shall be my ministers;)

22 as the stars of (the) heaven(s) may not be numbered, and the gravel of the sea may not be meted, so I shall multiply the seed of David, my servant, and (the) deacons, my ministers. (for as the host of heaven cannot be numbered, and as the sands of the sea cannot be measured, so I shall multiply in number the descendants of my servant David, and my ministers, the Levites.)
