Isaiah 45:3

The first strophe of the first half of this sixth prophecy (Isa 44:24.), the subject of which is Cyrus, the predicted restorer of Jerusalem, of the cities of Judah, and of the temple, is now followed by a second strophe (Isa 45:1-8), having for its subject Cyrus, the man through whose irresistible career of conquest the heathen would be brought to recognise the power of Jehovah, so that heavenly blessings would come down upon the earth. The naming of the great shepherd of the nations, and the address of him, are continued in Isa 45:1-3 : "Thus saith Jehovah to His anointed, to Koresh, whom I have taken by his right hand to subdue nations before him; and the loins of kings I ungird, to open before him doors and gates, that they may not continue shut. I shall go before thee, and level what is heaped up: gates of brass shall I break in pieces, and bolts of iron shall I smite to the ground. And I shall give thee treasures of darkness, and jewels of hidden places, that thou mayest know that I Jehovah am He who called out thy name, (even) the God of Israel." The words addressed to Cyrus by Jehovah commence in Isa 45:2, but promises applying to him force themselves into the introduction, being evoked by the mention of his name. He is the only king of the Gentiles whom Jehovah ever meshı̄chı̄ (my anointed; lxx τῷ χριστῷ μου). The fundamental principle of the politics of the empire of the world was all-absorbing selfishness. But the politics of Cyrus were pervaded by purer motives, and this brought him eternal honour. The very same thing which the spirit of Darius, the father of Xerxes, is represented as saying of him in the Persae of Aeschylus (v. 735), Θεὸς γὰρ οὐκ ἤχθησεν ὡς εὔφρων ἔφυ (for he was not hateful to God, because he was well-disposed), is here said b…

Cyrus was nominated, in the foregoing chapter, to be God's shepherd; more is said to him and more of him in this chapter, not only because he was to be instrumental in the release of the Jews out of their captivity, but because he was to be therein a type of the great Redeemer, and that release was to be typical of the great redemption from sin and death; for that was the salvation of which all the prophets witnessed. We have here, I. The great things which God would do for Cyrus, that he might be put into a capacity to release God's people (Isa 45:1-4). II. The proof God would hereby give of his eternal power and godhead, and his universal, incontestable, sovereignty (Isa 45:5-7). III. A prayer for the hastening of this deliverance (Isa 45:8). IV. A check to the unbelieving Jews, who quarrelled with God for the lengthening out of their captivity (Isa 45:9, Isa 45:10). V. Encouragement given to the believing Jews, who trusted in God and continued instant in prayer, assuring them that God would in due time accomplish this work by the hand of Cyrus (Isa 45:11-15). VI. A challenge given to the worshippers of idols and their doom read, and satisfaction given to the worshippers of the true God and their comfort secured, with an eye to the Mediator, who is made of God to us both righteousness and sanctification (Isa 45:16-25). And here, as in many other parts of this prophecy, there is much of Christ and of gospel grace.

45:3 so you may know: Cyrus’s victories provided factual proof that the Lord has the power to fulfill his plans, whereas idols and false gods do not (see 41:21-29).
