The Lord is my strength and song - He is the source of strength to me; and he is the subject of my praise. There is no ground of praise in myself for anything that I have done, but all is due to him.

And is become my salvation - He has saved me. I live because he preserved me. So we shall be saved in heaven solely because he saves us, and there, more than can be possible here, we shall say, "God is our strength and our song, and is become our salvation."

The Lord is my strength and song,.... It being in the name of the Lord the enemies of the psalmist were destroyed; and having obtained help of him when sore thrust at, he gives him all the glory, and ascribes nothing to himself. It was the Lord that strengthened him, helped him, and gave him the victory. The Lord is the author and giver of strength, natural and spiritual; he is the "strength" of the hearts and lives of his people, and of their salvation; and therefore is their "song", the matter of it: they sing of his nature and perfections, of his works of providence and grace, of his righteousness and salvation, as follows:

and is become my salvation; the author of temporal, spiritual, and eternal salvation; which the psalmist saw his interest in, and was assured of, and therefore sung praise on that account; see Exodus 15:2.

The LORD is my strength and {f} song, and is become my salvation.

(f) In that he was delivered, it came not from himself, not from the power of man, but only from God's favour, therefore he will praise him.

118:14 Salvation - My Saviour.

118:1-18 The account the psalmist here gives of his troubles is very applicable to Christ: many hated him without a cause; nay, the Lord himself chastened him sorely, bruised him, and put him to grief, that by his stripes we might be healed. God is sometimes the strength of his people, when he is not their song; they have spiritual supports, though they want spiritual delights. Whether the believer traces back his comfort to the everlasting goodness and mercy of God, or whether he looks forward to the blessing secured to him, he will find abundant cause for joy and praise. Every answer to our prayers is an evidence that the Lord is on our side; and then we need not fear what man can do unto us; we should conscientiously do our duty to all, and trust in him alone to accept and bless us. Let us seek to live to declare the works of God, and to encourage others to serve him and trust in him. Such were the triumphs of the Son of David, in the assurance that the good pleasure of the Lord should prosper in his hand.
