Contradiction with Jeremiah 33:20-21
This verse states that God's covenant with David can only be broken if the day and night cease, suggesting a perpetual promise, which seems to support Psalms 89:29 rather than contradict it. However, it introduces the condition of natural order cessation, which could be seen as a limitation.
Jeremiah 33:20-21: Thus saith the LORD; If ye can break my covenant of the day, and my covenant of the night, and that there should not be day and night in their season;
Contradiction with Hosea 3:4
This verse mentions that the children of Israel shall be without a king for many days, implying a break in Davidic lineage or rule, contradicting the everlasting nature implied in Psalms 89:29.
Hosea 3:4: For the children of Israel shall abide many days without a king, and without a prince, and without a sacrifice, and without an image, and without an ephod, and [without] teraphim: [image: Heb. a standing, or, statue, or, pillar]
Paradox #1
Psalms 89:29 talks about the promise of an everlasting dynasty or lineage. A possible contradiction could arise from historical events where the Davidic line did not continue to rule, notably after the Babylonian exile when the line of David was no longer on the throne of Israel or Judah. This could be seen as conflicting with the idea of an unbroken royal line.
