I am the Lord - I am Yahweh. Here is also a change in the address. In the previous verses, God had addressed the Messiah. Here he turns to the people, and assures them that he is the only true God, and that he will not suffer the praise that is due to him to be given to any other, or to any graven image. The name Yahweh signifies being, or essential existence (see the note at Isaiah 1:9). It is a name which is given to none but the true God, and which is everywhere in the Scriptures used to distinguish him from all others.

That is my name - That is the name which I have chosen by which to distinguish myself from all idols, and which I regard as appropriately expressive of my existence and perfections. Thus it is used in Psalm 83:18 (compare Psalm 96:5). "And my glory." The glory, honor, or praise that is due to me.

Will I not give - I will not allow it to ascribed to another; I will not allow another to assume or receive the honor which is due to me.

To another - To any other; whether it be man, or whether it be an idol. God claims that all appropriate honors should be rendered to him, and that men should cherish no opinions, maintain no doctrines, indulge in no feelings, that would be derogatory to the honor of his name. This declaration is designed to counteract the propensity everywhere manifest to attribute to man that which belongs to God, or to ascribe to our own wisdom, skill, or power, that which he alone can accomplish.

Neither my praise - The praise which is due to me. He would not permit graven images to receive the praise of having done that which he himself had accomplished.

I am the Lord - אני יהוה ani Yehovah. This is the famous tetragrammaton, or name of four letters, which we write Jehovah Yehovah, Yehveh, Yeveh, Jhuh, Javah, etc. The letters are Y H U H. The Jews never pronounce it, and the true pronunciation is utterly unknown.

That is my name - A name peculiar to myself.

I am the Lord, that is my name,.... Jehovah, a name expressive of his self-existence, eternity, and immutability; a name by which be made himself known to Israel of old, and which is peculiar to him, and does not belong to another, and so distinguishes him from all false gods; see Exodus 3:14 or, "Hu is my name" (p); to which "he himself the same", answers; see Psalm 102:27, compared with Hebrews 13:8 and this is one of the names of God with the Jews (q); as Hou is with the Turks to this day; which, in Arabic, signifies "him": that is, God, as Monsieur Thevenot (r) observes; see Isaiah 48:12,

and my glory will I not give to another; that is, to another god, to a strange god, to an idol; as that has not the nature, it ought not to have the name of deity, nor divine worship given to it: this the Lord will not admit of, but will punish those, be they Heathens, or are called Christians, that give the glory to idols that is due unto his name. This is not to be understood to the exclusion of the Son and Spirit, who are with the Father the one Jehovah, and share in the same glory; the Son is the brightness of his Father's glory, and the Spirit is the Spirit of glory, Hebrews 1:3 nor will he suffer the glory of the justification, salvation, and conversion of men, to be given to their works, will, and power, which is entirely due to his own grace, to the blood and righteousness of his Son, and to the energy of the divine Spirit:

neither my praise to graven images; which serves to explain the former clause, what is meant by his "glory", and who by "another", to whom he will not give it. Papists should observe this, for it respects not merely or only the graven images of the Heathens, but chiefly those among them that bear the Christian name; for this relates to New Testament times. The Targum is,

"and my glory, in which I am revealed to you, I will not give to another people; nor my praise to worshippers of images.''

Jehovah pledges His name and honour that this work of the Servant of Jehovah will be carried into effect. "I am Jehovah; that is my name, and my glory I give not to another, nor my renown to idols." That is His name, which affirms how truly He stands alone in His nature, and recals to mind the manifestations of His life, His power, and His grace from the very earliest times (cf., Exodus 3:15). He to whom this name belongs cannot permit the honour due to Him to be permanently transferred to sham gods. He has therefore made preparations for putting an end to idolatry. Cyrus does this provisionally by the tempestuous force of arms; and the Servant of Jehovah completes it by the spiritual force of His simple word, and of His gentle, unselfish love.

I am the LORD: that is my name: and my {o} glory will I not give to another, neither my praise to graven images.

(o) I will not permit my glory to be diminished: which I would do if I were not faithful.

42:8 The Lord - Heb. Jehovah: who have all being in and of myself, and give being to all my creatures. The everlasting, and unchangeable, and omnipotent God, who therefore both can, and will fulfil all my promises.

8. God turns from addressing Messiah to the people.

Lord-Jehovah: God's distinguishing and incommunicable name, indicating essential being and immutable faithfulness (compare Ex 6:3; Ps 83:18; 96:5; Ho 12:5).

my-that is due to Me, and to Me alone.

42:5-12 The work of redemption brings back man to the obedience he owes to God as his Maker. Christ is the light of the world. And by his grace he opens the understandings Satan has blinded, and sets at liberty from the bondage of sin. The Lord has supported his church. And now he makes new promises, which shall as certainly be fulfilled as the old ones were. When the Gentiles are brought into the church, he is glorified in them and by them. Let us give to God those things which are his, taking heed that we do not serve the creature more than the Creator.
