This people have I formed for myself - To preserve the remembrance of my name; to transmit the knowledge of the true God to future times, and to celebrate my praise (see the notes at Isaiah 43:1).

They shall show forth my praise - They shall celebrate my goodness; or, by their restoration to their own land, they shall show manifestly that they are my people.

This people have I formed for myself,.... The Gentiles, compared to a desert and wilderness, wild and uncultivated, distinguished from Jacob and Israel in the next verse, and the same with the chosen people before mentioned; who being chosen of God, and redeemed by Christ, are formed anew by the Spirit of Christ, made new creatures, regenerated, and transformed by the renewing of their minds, and conformed to the image of Christ, and having him formed in their souls, and principles of grace and holiness wrought in them; in consequence of which they reformed in their lives and conversation, and were also formed into a Gospel church state, and all this done by the Lord for himself, his service, and his glory. The Targum is,

"this people have I prepared for my worship:''

they shall show forth my praise; with their lips, by ascribing their formation to the power and grace of God, and even their whole salvation to it, and express their thankfulness for the same; and likewise by their actions, by a subjection to the ordinances of the Gospel, and by their lives and conversations being agreeably to it. Joseph Kimchi, as Abendana observes, interprets this people of the beasts of the field, spoken of in the preceding verse, that should honour the Lord, and here said to be formed for himself, and should show forth his praise; and which is taken notice of to aggravate the sins of the people of the Jews, who called not on the Lord, &c. as in the following verses; so the ants and conies are called a people not strong, and the locusts a people great and strong, Proverbs 30:25.

This people have I formed for myself; they shall shew forth my praise.

21. This people-namely, The same as "My people, My chosen" (see Isa 43:1, 7; Ps 102:18).

my praise-on account of the many and great benefits conferred on them, especially their restoration.

43:14-21 The deliverance from Babylon is foretold, but there is reference to greater events. The redemption of sinners by Christ, the conversion of the Gentiles, and the recall of the Jews, are described. All that is to be done to rescue sinners, and to bring the believer to glory, is little, compared with that wondrous work of love, the redemption of man.
