Deuteronomy 32:4

“[He is] the rock, etc.] That is, Jehovah is the rock, whose name Moses proposed to publish; and our God, to whom the heavens and the earth are called upon to ascribe greatness, even Christ the rock of salvation: here begins the song; the first word in it is very emphatic; it has a letter in it larger than usual, to denote the greatness of this Person, and to make it observable; he is “this” or “that rock” f571, by way of eminence, that rock and stone of Israel, Jacob prophesied of, which was typified by the rock Moses had smitten in the wilderness, and which, no doubt, he knew, as the Apostle Paul did, that it was a type of Christ, and had taught the Israelites so to understand it; and…”

“He is the Rock--a word expressive of power and stability. The application of it in this passage is to declare that God had been true to His covenant with their fathers and them. Nothing that He had promised had failed; so that if their national experience had been painfully checkered by severe and protracted trials, notwithstanding the brightest promises, that result was traceable to their own undutiful and perverse conduct; not to any vacillation or unfaithfulness on the part of God (Jam 1:17), whose procedure was marked by justice and judgment, whether they had been exalted to prosperity or plunged into the depths of affliction.”

“Song of Moses If Deuteronomy 32:1-3 be regarded as the introduction, and Deuteronomy 32:43 as the conclusion, the main contents of the song may be grouped under three heads, namely, (1) Deuteronomy 32:4-18, the faithfulness of God, the faithlessness of Israel; (2) Deuteronomy 32:19-33, the chastisement and the need of its infliction by God; (3) Deuteronomy 32:34-42, God’s compassion upon the low and humbled state of His people. The Song differs signally in diction and idiom from the preceding chapters; just as a lyrical passage is conceived in modes of thought wholly unlike those which belong to narrative or exhortation, and is uttered in different phraseology.

“A rock - As for the stability of his nature, and invincibleness of his power, so also for his fixedness and immutability in his counsels and promises and ways; so that is there shall be a sad change in your affairs, remember that this proceeds from yourselves and from the change of your ways towards God, and not from God, in whom there is no variableness or shadow of change, Jam 1:17.

A God of truth - Constant to his promises: you cannot accuse him of any unfaithfulness to this day. Deuteronomy 32:5”

“32:4 the Rock: This metaphor represents the Lord as strong, stable, and reliable; he is more than capable of providing righteousness and justice (see 32:15, 18, 30; Hab 1:12).”
