But before the assize opens, the heavens, which had been summoned to behold, declare beforehand His righteousness, as manifested by the fact that He is about to judge His people. The Selah indicates that a long-drawn swell of music fills the expectant pause before the Judge speaks from His tribunal.
The second part (vv. 7-15) deals with one of the two permanent tendencies which work for the corruption of religion--namely, the reliance on external worship, and neglect of the emotions of thankfulness and trust. God appeals first to the relation into which He has entered with the people, as giving Him the right to judge. There may be a reference to the Mosaic formula, "I am Jehovah, thy God," which is here converted, in accordance with the usage of this book of the Psalter, into "God (Elohim), thy God." The formula which was the seal of laws when enacted is also the warrant for the action of the Judge. He has no fault to find with the external acts of worship. They are abundant and "continually before Him." Surely this declaration at the outset sets aside the notion that the psalmist was launching a polemic against sacrifices _per se_. It distinctly takes the ground that the habitual offering of these was pleasing to the Judge. Their presentation continually is not reproved, but approved. What then is condemned? Surely it can be nothing but sacrifice without the thanksgiving and prayer required in vv. 14, 15. The irony of vv. 9-13 is directed against the folly of believing that in sacrifice itself God delighted; but the shafts are pointless as against offerings which are embodied gratitude and trust. The gross stupidity of supposing that man's gift makes the offering to be God's more truly than before is laid bare in the fine, sympathetic glance at the free, wild life of forest, mountain, and plain, which is all God's possession, and present to His upholding thought, and by the side of which man's folds are very small affairs. "The cattle" in ver. 10 are not, as usually, domesticated animals, but the larger wild animals. They graze or roam "on the mountains of a thousand"--a harsh expression, best taken, perhaps, as meaning mountains where thousands [of the cattle] are. But the omission of one letter gives the more natural reading "mountains of God" (_cf._ Psalm xxxvi. 6). It is adopted by Olshausen and Cheyne, and smooths the construction, but has against it its obliteration of the fine thought of the multitudes of creatures peopling the untravelled hills. The word rendered "whatever moves" is obscure; but that meaning is accepted by most. Cheyne in his Commentary gives as alternative "that which comes forth abundantly," and in "Orig. of Psalt.," 473, "offspring." All these are "with Me"--_i.e._, present to His mind--a parallel to "I know" in the first clause of the same verse.
Vv. 12, 13, turn the stream of irony on another absurdity involved in the superstition attacked--the grossly material thought of God involved in it. What good do bulls' flesh and goats' blood do to Him? But if these are expressions of thankful love, they are delightsome to Him. Therefore the section ends with the declaration that the true sacrifice is thanksgiving and the discharge of vows. Men honour God by asking and taking, not by giving. They glorify Him when, by calling on Him in trouble, they are delivered; and then, by thankfulness and service, as well as by the evidence which their experience gives that prayer is not in vain, they again glorify Him. All sacrifices are God's before they are offered, and do not become any more His by being offered. He neither needs nor can partake of material sustenance. But men's hearts are not His without their glad surrender, in the same way as after it; and thankful love, trust, and obedience are as the food of God, sacrifices acceptable, well-pleasing to Him.
