Jeremiah 33:17-21

For this is what the Lord says: ‘David shall not lack a man to sit on the throne of the house of Israel;

and the Levitical priests shall not lack a man before Me to offer burnt offerings, to burn grain offerings, and to prepare sacrifices continually.’ ”

And the word of the Lord came to Jeremiah, saying,

“This is what the Lord says: ‘If you can break My covenant for the day and My covenant for the night, so that day and night do not occur at their proper time,

then My covenant with David My servant may also be broken, so that he will not have a son to reign on his throne, and with the Levitical priests, My ministers.
