43:1 Thus says the Lord emphasizes the Author of the prophecy and the certainty that it will be fulfilled (49:8; 50:1; 56:1). The words created and formed allude to the creation of the human race in Gen. 1; 2. The Hebrew verb translated created means “to fashion anew”—a divine activity, and is the same key word used in Gen. 1:1 (40:26; 41:20; 45:12, 18; 57:19; 65:17, 18). The second verb formed means “to shape,” to fashion as a potter, and is used in Gen. 2:7 of God fashioning the body of the man from the dust of the earth. The use of these verbs here suggests that the Lord’s creation of Israel as a people was as decisive an act as His creation of human beings at the beginning. In the same way, the NT describes Christians as new creations in Christ (2 Cor. 5:17; Eph. 2:10). by your name: The Lord’s use of name demonstrates His intimate relationship with the Israelites. He had revealed His name to the people (Ex. 6:2–8) and declared their name to Pharaoh (Ex. 4:22).
43:1 formed. The only explanation for the ongoing existence of the nation of Israel is God’s sovereign grace, which brought her into existence from nothing (cf. Dt 7:6–11) and sustains her. Since she was God’s creation, she could find comfort in knowing that no one or nothing can destroy her, not even her own wickedness (cf. 43:18–25; Ro 11:1, 2, 25–27). Jacob … Israel. This double designation (cf. Ge 32:28) for God’s chosen nation is used by Isaiah 21 times, 16 of them in chaps. 40–49 (9:8; 10:20; 14:1; 27:6; 29:23; 40:27; 41:8, 14; 42:24; 43:1, 22, 28; 44:1, 21, 23; 45:4; 46:3; 48:1, 12; 49:5, 6). This speaks of the Lord’s special attachment to Abraham’s physical seed. Do not fear. The Lord repeated His word, relieving Israel’s fear (35:4; 41:10, 13, 14; cf. 7:4). redeemed. God’s redemption of His people from exile is not to be complete until His Servant returns to reign over the faithful remnant in the land of Israel who have believed on Jesus Christ (cf. Zec 12:10–13:1; Ro 11:25–27; Rev 11:13). The limited return from Babylon only typified the final return. See note on 43:14.
43:1 Fear not. Knowing what they deserve, the people should fear; but hearing of their Redeemer’s choice and promise, they should not fear. redeemed. See note on 41:14. you are mine. What defines them is not their guilty blindness (42:18–25) but the grace of the One who says, “You are mine” (cf. Ex. 6:7).
43:1 he who created you, Jacob Yahweh is responsible for both Israel’s creation as living beings and their formation as a nation. Isaiah uses creation language to emphasize God’s power as Creator and His special attention to His chosen people.
I have redeemed you God already identified Himself as their Redeemer in 41:14. Now, He reminds them of the relationship between Redeemer and redeemed. The exiles have no reason to fear, because salvation is assured.
Compare Exod 6:6–7 where Yahweh similarly promises to redeem Israel and take them as His people.
I have called you by your name Isaiah’s speeches throughout this section emphasize Yahweh’s special choice of Israel (see Isa 41:8–9; 45:3–4).
43:1 God claims Israel as His own on the basis of four factors: (1) creation, (2) formation, (3) redemption, and (4) naming, which according to Oriental custom signified ownership (cf. Rom. 8:29, note).
43:1 Calling a person by name indicates a high level of familiarity. The phrase might even hint at the fact that God gave them their names, an act to indicate superiority and perhaps even ownership. God gave Israel its name when he changed the name of the patriarch Jacob to Israel (Gn 32:28). The intention of this pronouncement is expressed clearly at the start (Do not fear; see also 43:5). God informed his people about their coming deliverance to keep them from caving in to fear.
