Jehovah is holy, not only because lifted above and separated from creatural limitations, but because of His righteousness. The second strophe therefore proclaims that all His dominion is based on uprightness, and is a continual passing of that into acts of "judgment and righteousness." The "And" at the beginning of ver. 4, following the refrain, is singular, and has led many commentators to link the words with ver. 3_a_, and, taking the refrain as parenthetical, to render, "Let them give thanks to Thy great and dread name, [for it is holy], and [to] the strength of the King [who] loveth," etc. But the presence of the refrain is an insuperable bar to this rendering. Others, as Delitzsch and Cheyne, regard "the strength of the king" as dependent on "established" in ver. 4_b_, and suppose that the theocratic monarch of Israel is represented as under Jehovah's protection, if he reigns righteously. But surely one King only is spoken of in this psalm, and it is the inmost principle and outward acts of His rule which are stated as the psalmist's reason for summoning men to prostrate themselves at His footstool. The "And" at the beginning of the strophe links its whole thought with that of the preceding, and declares eloquently how closely knit together are Jehovah's exaltation and His righteousness. The singer is in haste to assert the essentially moral character of infinite power. Delitzsch thinks that love cannot be predicated of "strength," but only of the possessor of strength; but surely that is applying the measuring line of prosaic accuracy to lyric fervour. The intertwining of Divine power and righteousness could not be more strongly asserted than by that very intelligible attribution to His power of the emotion of love, impelling it ever to seek union with uprightness. He is no arbitrary ruler. His reign is for the furtherance of justice. Its basis is "equity," and its separate acts are "judgment and righteousness." These have been done in and for Jacob. Therefore the call to worship rings out again. It is addressed to an undefined multitude, which, as the tone of all this group of psalms leads us to suppose, includes the whole race of man. They are summoned to lift high the praise of Him who in Himself is so high, and to cast themselves low in prostrate adoration at His footstool--_i.e._, at His sanctuary on Zion (ver. 9). Thus again, in the centre strophe of this psalm, as in Psalms xcvi. and xcviii., mankind are called to praise the God who has revealed Himself in Israel; but while in the former of these two psalms worship was represented as sacrificial, and in the second as loud music of voice and instrument, here silent prostration is the fitting praise of the holiness of the infinitely exalted Jehovah.
