For I am Jehovah thy God. The Prophet had already shewn where the hope of salvation ought to be placed, so as to hold out against every attack; that is, when we are convinced that God is our God, and is on our side. He now lays down the same doctrine, but in different words; and yet the repetition is not superfluous, for we know how easily this doctrine slips out of our minds, even though it be frequently repeated; and it was impossible to bestow excessive commendation on this promise, which it is so difficult to root in our hearts. Let us therefore know that we shall have a prosperous issue of all our contests, for the Lord is present with us; and whenever we are attacked by any severe contest, let us learn to look to Him; for if we hesitate and look hither and thither, we shall never enjoy peace of mind. When he calls himself our God, he not only mentions his power, but gives proof of his goodness, which he intends to exercise towards us; for it would not be enough to be convinced of the power of God, if we were not equally certain of his love; and even when we are terrified by the mention of his power alone, his goodness is well fitted to give us peace. Taking hold of thy right hand, and saying to thee. He now speaks about "taking hold of the hand," and about his voice; for it is of great importance to us to believe the signs which God has given us of his love, and to connect with them the doctrine which assures us of his eternal favor. The word saying is therefore highly emphatic; for we must remain in suspense till the Lord speak, whose voice alone can remove fear and bring peace. If, then, we desire to have composure of mind, and to conquer the vexations which come upon us from various quarters, we must pay close attention to his voice, so as never to withdraw our mind from it; for they who refuse to hear this voice of God, or do not hear it attentively, must be miserably tormented by continual doubt and uncertainty.

For I the Lord thy God will hold thy right hand,.... Take hold of it, join in league and alliance with his people as it were, go hand in hand with them; and having such an one with them, and on their side, they need fear no enemy: or it is expressive of great freedom, familiarity, and friendship, which may assure believers of the strong affection of God towards them; and they may conclude themselves safe, being held by him as a child in the hand of its parents, which is then not afraid of anything. The Lord holds the right hand of his people, teaching them to walk by faith, leading them into his presence, and to communion with himself, and keeps them from falling: or, he "will strengthen their right hand" (r); to do his work and service, and oppose their enemies; or he will relieve their wants, and fill their hands with his good things, which is sometimes the sense of the phrase, Ezekiel 16:45,
saying unto thee, fear not, I will help thee; as one friend takes another by the hand in distress, and bids him be of good cheer, promising him all needful assistance and supply. See Gill on Isaiah 41:10.

Will hold - Will enable thee to vanquish all thine enemies.
