Jesaja 45:4

A second and third object are introduced by a second and third למען. "For the sake of my servant Jacob, and Israel my chosen, I called thee hither by name, surnamed thee when thou knewest me not. I Jehovah, and there is none else, beside me no God: I equipped thee when thou knewest me not; that they may know from the rising of the sun, and its going down, that there is none without me: I Jehovah, and there is none else, former of the light, and creator of the darkness; founder of peace, and creator of evil: I Jehovah am He who worketh all this." The ואקרא which follows the second reason assigned like an apodosis, is construed doubly: "I called to thee, calling thee by name." The parallel אכנּך refers to such titles of honour as "my shepherd" and "my anointed," which had been given to him by Jehovah. This calling, distinguishing, and girding, i.e., this equipment of Cyrus, took place at a time when Cyrus knew nothing as yet of Jehovah, and by this very fact Jehovah made known His sole Deity. The meaning is, not that it occurred while he was still worshipping false gods, but, as the refrain-like repetition of the words "though thou hast not know me" affirms with strong emphasis, before he had been brought into existence, or could know anything of Jehovah. The passage is to be explained in the same way as Jer 1:5, "Before I formed thee in the womb, I knew thee" (see Psychol. pp. 36, 37, 39); and what the God of prophecy here claims for Himself, must not be questioned by false criticism, or weakened down by false apologetics (i.e., by giving up the proper name Cyrus as a gloss in Isa 44:28 and Isa 45:1; or generalizing it into a king's name, such as Pharaoh, Abimelech, or Agag). The third and last object of this predicted and realized success of the oppressor of nations and…

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.

45:4-5 I call you by name: Cyrus did not know the Lord, but the Lord knew him. Isaiah predicted the rescuer Cyrus by name 150 years in advance. This prophecy would prove to the exiles that the Lord is indeed God and that he knows the future.
