Vv. 5, 6, assign the reason for the praise of the heavens--Jehovah's creative act, His sustaining power and His "law," the utterance of His will to which they conform. Ver. 6_a_ emphatically asserts, by expressing the "He," which is in Hebrew usually included in the verb, that it is Jehovah and none other who "preserves the stars from wrong." "Preservation is continuous creation." The meaning of the close of ver. 6_b_ is doubtful, if the existing text is adhered to. It reads literally "and [it?] shall not pass." The unexpressed nominative is by some taken to be the before-mentioned "law," and "pass" to mean _cease to be in force_ or _be transgressed_. Others take the singular verb as being used distributively, and so render "None of them transgresses." But a very slight alteration gives the plural verb, which makes all plain.
In these starry depths obedience reigns; it is only on earth that a being lives who can and will break the merciful barriers of Jehovah's law. Therefore, from that untroubled region of perfect service comes a purer song of praise, though it can never have the pathetic harmonies of that which issues from rebels brought back to allegiance.
The summons to the earth begins with the lowest places, as that to the heavens did with the highest. The psalmist knows little of the uncouth forms that may wallow in ocean depths, but he is sure that they too, in their sunless abodes, can praise Jehovah. From the ocean the psalm rises to the air, before it, as it were, settles down on earth. Ver. 8 may refer to contemporaneous phenomena, and, if so, describes a wild storm hurtling through the lower atmosphere. The verbal arrangement in ver. 8_a_ is that of inverted parallelism, in which "fire" corresponds to "smoke" and "hail" to "snow." Lightning and hail, which often occur together, are similarly connected in Psalm xviii. 12. But it is difficult to explain "snow and smoke," if regarded as accompaniments of the former pair--fire and hail. Rather they seem to describe another set of meteorological phenomena, a winter storm, in which the air is thick with flakes as if charged with smoke, while the preceding words refer to a summer's thunderstorm. The resemblance to the two pictures in the preceding psalm, one of the time of the latter rains and one of bitter winter weather, is noticeable. The storm-wind, which drives all these formidable agents through the air, in its utmost fury is a servant. As in Psalm cvii. 25, it obeys God's command.
The solid earth itself, as represented by its loftiest summits which pierce the air; vegetable life, as represented by the two classes of fruit-bearing and forest trees; animals in their orders, wild and domestic; the lowest worm that crawls and the light-winged bird that soars,--these all have voices to praise God. The song has been steadily rising in the scale of being from inanimate to animated creatures, and last it summons man, in whom creation's praise becomes vocal and conscious.
All men, without distinction of rank, age, or sex, have the same obligation and privilege of praise. Kings are most kingly when they cast their crowns before Him. Judges are wise when they sit as His vicegerents. The buoyant vigour of youth is purest when used with remembrance of the Creator; the maiden's voice is never so sweet as in hymns to Jehovah. The memories and feebleness of age are hallowed and strengthened by recognition of the God who can renew failing energy and soothe sad remembrances; and the child's opening powers are preserved from stain and distortion, by drawing near to Him in whose praise the extremes of life find common ground. The young man's strong bass, the maiden's clear alto, the old man's quavering notes, the child's fresh treble, should blend in the song.
Ver. 13 gives the reason for the praise of earth, but especially of man, with very significant difference from that assigned in vv. 5, 6. "His name is exalted." He has manifested Himself to eyes that can see, and has shown forth His transcendent majesty. Man's praise is to be based not only on the Revelation of God in Nature, but on that higher one in His dealings with men, and especially with Israel. This chief reason for praise is assigned in ver. 14, and indeed underlies the whole psalm. "He has lifted up a horn for His people," delivering them from their humiliation and captivity, and setting them again in their land. Thereby He has provided all His favoured ones with occasion for praise. The condensed language of ver. 14_b_ is susceptible of different constructions and meanings. Some would understand the verb from _a_ as repeated before "praise," and take the meaning to be "He exalts the praise [_i.e._, the glory] of His beloved," but it is improbable that praise here should mean anything but that rendered to God. The simplest explanation of the words is that they are in apposition to the preceding clause, and declare that Jehovah, by "exalting a horn to His people," has given them especially occasion to praise Him. Israel is further designated as "a people near to Him." It is a nation of priests, having the privilege of access to His presence; and, in the consciousness of this dignity, "comes forward in this psalm as the leader of all the creatures in their praise of God, and strikes up a hallelujah that is to be joined in by heaven and earth" (Delitzsch).
