In Jeremiah 33:17, Jehovah, the Lord God had covenant with King David.
In the same book, and after three verses,
In Jeremiah 33:21 Jehovah had broken his covenant with King David.
It is impossible for the Lord God to change his word.
So, either one of the two verses of Jeremiah is forged.
In the Quran (Verse 50:29), Allah says:
1) My word cannot be altered, twisted or changed and
2) I am not unjust to servants.
Jeremiah 33:17 and 21
King James Version

21Then may also my covenant be broken with David my servant, that he should not have a son to reign upon his throne; and with the Levites the priests, my ministers.
English Standard Version
17″For thus says the LORD: David shall never lack a man to sit on the throne of the house of Israel,
21 then also my covenant with David my servant may be broken, so that he shall not have a son to reign on his throne, and my covenant with the Levitical priests my ministers.
