Psalms 99:4

“The king’s strength - The word king here undoubtedly refers to God as a king, Psalms 99:1. The word rendered “strength,” means power, force; and the reference here is to what constitutes the main strength or power of his character and government. It is rendered in the Septuagint, τιμή timē - “honor.” So in the Latin Vulgate - ”honor.” DeWette renders it, “The praise of the king who loves judgment.” So Rosenmuller, “Let them praise the strength - the power - of the king who loves judgment.” But perhaps our common version best expresses the sense, that whatever there is in the character of the “king,” that is God, which constitutes strength, or gives power to his administration, is favorable…”

“Judgment - Though his dominion be absolute, and his power irresistible, yet he manages it with righteousness. The king's strength is by a known Hebraism put for the strong, or powerful king. Equity - In all thy proceedings. Psalms 99:5”

“99:4 The qualities of the Lord’s rule include strength, justice, love, fairness, and righteousness (see 93:4; 97:2, 6-7, 12; 98:2-3, 9; 138:6).”

“The second Sanctus celebrates Jahve with respect to His continuous righteous rule in Israel. The majority of expositors construe it: "And (they shall praise) the might of the king, who loves right;" but this joining of the clause on to יודוּ over the refrain that stands in the way is hazardous. Neither can ועז מלך משׁפּט אהב, however, be an independent clause, since אהב cannot be said of עז, but only of its possessor. And the dividing of the verse at אהב, adopted by the lxx, will therefore not hold good. משפט אהב is an attributive clause to מלך in the same position as in Psa 11:7; and עז, with what appertains to it, is the object to כּוננתּ placed first, which has the king's throne as its…”
