Verse 3. - He hath remembered his mercy and his truth towards the house of Israel. The judgment of the nations involves mercy and deliverance to Israel, which is oppressed by them; and thus manifests God's faithfulness towards them. All the ends of the earth have seen the salvation of our God (comp. ver. 2 and Isaiah 52:10).

98:1-3 A song of praise for redeeming love is a new song, a mystery hidden from ages and generations. Converts sing a new song, very different from what they had sung. If the grace of God put a new heart into our breasts, it will put a new song into our mouths. Let this new song be sung to the praise of God, in consideration of the wonders he has wrought. The Redeemer has overcome all difficulties in the way of our redemption, and was not discouraged by the services or sufferings appointed him. Let us praise him for the discoveries made to the world of the work of redemption; his salvation and his righteousness fulfilling the prophecies and promises of the Old Testament. In pursuance of this design, God raised up his Son Jesus to be not only a Light to lighten the Gentiles, but the glory of his people Israel. Surely it behoves us to inquire whether his holy arm hath gotten the victory in our hearts, over the power of Satan, unbelief, and sin? If this be our happy case, we shall exchange all light songs of vanity for songs of joy and thanksgiving; our lives will celebrate the Redeemer's praise.He hath remembered his mercy and his truth toward the house of Israel,.... His mercy promised them, in raising up a Saviour to them, one that should be the glory of them; and his truth, in fulfilling that and every other promise concerning him; see Luke 1:72,

all the ends of the earth have seen the salvation of our God; either Christ himself, who is the salvation or Saviour of God's appointing, providing, and sending; or the salvation which he has wrought out, the Gospel declaring it; which has been sent throughout the world; and many in all parts of it, even in the most distant parts of it, in the very ends of it, have been made to see the nature, want, worth, and value of it; not every individual person in the world, but some in the several parts, and in the remote corners of it, whither the Gospel has been or will be sent; see Isaiah 52:10.
