While the psalmist speaks the swift tempest has come down with a roar and a crash on the northern mountains, and Lebanon and "Sirion" (a Sidonian name for Hermon) reel, and the firm-boled, stately cedars are shivered. The structure of the verses already noticed, in which the second clause reduplicates, with some specialising, the thought of the first, makes it probable that in ver. 6 _a_ the mountains, and not the cedars, are meant by them. The trees are broken; the mountains shake. An emendation has been proposed, by which "Lebanon" should be transferred from ver. 5 to ver. 6 and substituted for "them" so as to bring out this meaning more smoothly, but the roughness of putting the pronoun in the first clause and the nouns to which it refers in the second is not so considerable as to require the change. The image of the mountains "skipping" sounds exaggerated to Western ears, but is not infrequent in Scripture, and in the present instance is simply a strong way of expressing the violence of the storm, which seems even to shake the steadfast mountains that keep guard over the furthest borders of the land. Nor are we to forget that here there may be some hint of a parable in nature. The heights are thunder-smitten; the valleys are safe. "The day of the Lord shall be upon all the cedars of Lebanon that are high and lifted up, ... and upon all the high mountains" (Isa. ii. 13, 14).
The two-claused verses are interrupted by one of a single clause (ver. 7), the brevity of which vividly suggests the suddenness and speed of the flash: "The voice of Jehovah cleaves [or, hews out] fire flames." The thunder is conceived of as the principal phenomenon and as creating the lightning, as if it hewed out the flash from the dark mass of cloud. A corrected accentuation of this short verse divides it into three parts, perhaps representing the triple zigzag; but in any case the one solitary, sudden fork, blazing fiercely for a moment and then swallowed up in the gloom, is marvellously given. It is further to be noted that this single lightning gleam parts the description of the storm into two, the former part painting it as in the north, the latter as in the extreme south. It has swept over the whole length of the land, while we have been watching the flash. Now it is rolling over the wide plain of the southern desert. The precise position of Kadesh is keenly debated, but it was certainly in the eastern part of the desert region on the southern border. It, too, shakes, low-lying as it is; and far and wide over its uninhabited levels the tempest ranges. Its effects there are variously understood. The parallelism of clauses and the fact that nowhere else in the picture is animal life introduced give great probability to the very slight alteration required in ver. 9 _a_, in order to yield the rendering "pierces the oaks" (Cheyne), instead of "makes the hinds calve" which harmonises admirably with the next clause; but, on the other hand, the premature dropping of the young of wild animals from fear is said to be an authentic fact, and gives a defensible trait to the picture, which is perhaps none the less striking for the introduction of one small piece of animated nature. In any case the next clause paints the dishevelled forest trees, with scarred bark, broken boughs, and strewn leaves, after the fierce roar and flash, wind and rain, have swept over them. The southern border must have been very unlike its present self, or the poet's thoughts must have travelled eastwards, among the oaks on the other side of the Arabah, if the local colouring of ver. 9 is correct.
While tumult of storm and crash of thunder have been raging and rolling below, the singer hears "a deeper voice across the storm," the songs of the "sons of God" in the temple palace above, chanting the praise to which he had summoned them. "In His temple every one is saying, Glory!" That is the issue of all storms. The clear eyes of the angels see, and their "loud uplifted trumpets" celebrate, the lustrous self-manifestation of Jehovah, who rides upon the storm, and makes the rush of the thunder minister to the fruitfulness of earth.
