Psalms 89:43

Thou hast also turned the edge of his sword, and hast not made him to stand in the battle.

The verse portrays defeat in combat, for God Himself turns aside the edge of the warrior's sword and does not make him stand firm in the battle, taking away strength to fight. The one whose sword is turned back is the seed of David, and this turning belongs to God's casting off and abhorring him, exalting the right hand of his adversaries against him, profaning his crown to the ground, making his glory to cease and casting his throne down to the ground. It gives voice to the sorrows and afflictions of the Hebrew captives in the Babylonian captivity, especially in its latter part under Belshazzar, when Jewish persecution and distress were severe.

That rejection came because the promise that David's throne should be established forever was conditioned on his seed keeping God's statutes and judgments and faithfully obeying and serving Him, but Solomon departed from God and succeeding generations of David did evil, so throne and kingdom were taken from them when Zedekiah fell captive to the king of Babylon, and for thousands of years no throne of David has been possessed by his seed, a fact history confirms, since David's personal earthly throne was cast to the ground many centuries ago. In this way the psalm holds forth a conditional promise of a kingdom to the descendants of Jacob, which they forfeited under the old covenant and can regain only through an interest in Jesus, now Prince and soon to be crowned King. The verse stands as part of a prophecy concerning David and his greater Son, Jesus Christ.

The psalm is David's prophetic song of deliverance, joined to the triumph of Christ's resurrection. The promises that the seed should be established forever and the throne built up to all generations belong only to Christ, far greater than David and Solomon, and to His blessed seed. The psalm shows that God's covenant stands fast with Christ, and that covenant is the Ten Commandments, which are not abolished. The psalm to which the verse belongs is among the Old Testament prophecies appealed to for the reign of Christ, the inheritance of the saints, and the return of the Jews to special favor and an earthly place in the Christian dispensation.
