Psalm 89:29 says that God will make the descendants of the chosen king endure forever and that his throne will last as long as the heavens exist. The verse is a promise of lasting royal dynasty, spoken within a longer poem about God’s covenant with David. The speaker is the psalmist, who is recounting God’s own words about the king he has chosen, so the verse reports a divine commitment to a specific line of rulers.
I will also make his offspring endure forever, and his throne as the days of heaven.

What Psalm 89:29 Means
The phrase “I will also make his offspring endure forever” describes God as the one who secures the future of the king’s family. The Hebrew idea of “offspring” here points to the king’s descendants as a continuing line, not just a single heir. God is the active party in making this line last, which means the promise rests on his faithfulness rather than on the strength or merit of any one ruler.
The second half, “his throne as the days of heaven,” uses a vivid picture. The heavens seemed permanent to ancient readers, so comparing the throne’s duration to their days emphasizes a length that feels almost unbounded. The verse does not promise that every king in the line will be righteous, and the surrounding verses in fact address failure directly. What it promises is that God’s covenant with this dynasty will not simply disappear.
The Context of Psalm 89:29
Psalm 89 is a wisdom and worship psalm traditionally attributed to Ethan the Ezrahite, and it is usually read as a meditation on God’s covenant with David (compare 2 Samuel 7). The poem moves from praise of God’s faithfulness, to the covenant promise itself, and then to a lament over the apparent collapse of the Davidic kingdom. Verse 29 sits in the middle of God’s speech about David, where the divine voice affirms what he has pledged.
The verses just before and after change how the promise reads. Verse 28 speaks of God’s loving kindness and covenant standing firm, and verses 30 through 32 warn that the king’s children may forsake God’s law and face discipline. So the promise of an enduring line is not a license for disobedience. It is a covenant commitment that holds even when the descendants fail, which is why the psalm can later lament the king’s humiliation and still hold onto God’s word.
Key Phrases in Psalm 89:29
2 Samuel 7:16
Your house and your kingdom will be made sure forever before you. Your throne will be established forever.”’”
(WEB)
This is the original covenant promise to David about his house and kingdom being made sure forever. Reading it alongside Psalm 89:29 shows how the psalm builds directly on that earlier divine word.
Isaiah 9:7
Of the increase of his government and of peace there shall be no end, on David’s throne, and on his kingdom, to establish it, and to uphold it with justice and with righteousness from that time on, even forever. The zeal of the LORD of Armies will perform this.

Isaiah describes the endless increase of government and peace on the throne of David. It helps you see how later prophets carried the hope of an enduring Davidic reign forward into expectation of a coming king.
