the faithless nation, when He punished it for its apostasy (just as in Deu 4:26; Deu 30:19; Deu 31:28-29, heaven and earth are appealed to as witnesses against rebellious Israel), but also inasmuch as heaven and earth would be affected by the judgment which God poured out upon faithless Israel and the nations, to avenge the blood of His servants (Deu 32:43); since the faithfulness and righteousness of God would thus become manifest in heaven and on earth, and the universe be sanctified and glorified thereby. The vav consec. before אדבּרה expresses the desired or intended sequel: so that I may then speak, or “so will I then speak” (vid., Köhler on Hagg. p. 44, note).
verses 2-3
But because what was about to be announced was of such importance throughout, he desired that the words should trickle down like rain and dew upon grass and herb. The point of comparison lies in the refreshing, fertilizing, and enlivening power of the dew and rain. Might the song exert the same upon the hearts of the hearers. לקח, accepting, then, in a passive sense, that which is accepted, instruction (doctrine, Pro 16:21, Pro 16:23; Isa 29:24). To “publish the name of the Lord:” lit., call, i.e., proclaim (not “call upon”), or praise. It was not by himself alone that Moses desired to praise the name of the Lord; the hearers of his song were also to join in this praise. The second clause requires this: “give ye (i.e., ascribe by word and conduct) greatness to our God.” גּדל, applied here to God (as in Deu 3:24; Deu 5:21; Deu 9:26; Deu 11:2), which is only repeated again in Psa 150:2, is the greatness manifested by God in His acts of omnipotence; it is similar in meaning to the term “glory” in Psa 29:1-2; Psa 96:7-8.
verses 4-5
“The Rock - blameless is His work; for all His ways are right: a God of faithfulness, and without injustice; just and righteous is He. Corruptly acts towards Him, not His children; their spot, a perverse and crooked generation.” הצּוּר is placed first absolutely, to give it the greater prominence. God is called “the rock,” as the unchangeable refuge, who grants a firm defence and secure resort to His people, by virtue of His unchangeableness or impregnable firmness (see the synonym, “the Stone of Israel,” in Gen 49:24). This epithet points to the Mosaic age; and this is clearly shown by the use made of this title of God (Zur) in the construction of surnames in the Mosaic era; such, for example, as Pedahzur (Num 1:10), which is equivalent to Pedahel (“God-redeemed,” Num 34:28), Elizur (Num 1:5), Zuriel (Num 3:35), and Zurishaddai (Num 1:6; Num 2:12). David, who had so often experienced the rock-like protection of his God, adopted it in his
