1 (To the chief Musician on Neginoth, A Psalm or Song.) God be merciful unto us, and bless us; and cause his face to shine upon us; Selah.
2 That thy way may be known upon earth, thy saving health among all nations.
3 Let the people praise thee, O God; let all the people praise thee.
4 O let the nations be glad and sing for joy: for thou shalt judge the people righteously, and govern the nations upon earth. Selah.
5 Let the people praise thee, O God; let all the people praise thee.
6 Then shall the earth yield her increase; and God, even our own God, shall bless us.
7 God shall bless us; and all the ends of the earth shall fear him.
A prayer for the enlargement of Christ's kingdom.- All our happiness comes from God's mercy; therefore the first thing prayed for is, God be merciful to us, to us sinners, and pardon our sins. Pardon is conveyed by God's blessing, and secured in that. If we, by faith, walk with God, we may hope that his face will shine on us. The psalmist passes on to a prayer for the conversion of the Gentiles, which shows that the Old Testament saints desired that their advantages might also be enjoyed by others. And many Scripture prophecies and promises are wrapped up in prayers: the answer to the prayer of the church is as sure as the performance of God's promises. The joy wished to the nations, is holy joy. Let them be glad that by his providence the Lord will overrule the affairs of kingdoms; that even the kingdoms of this world shall became the kingdom of the Lord, and of his Christ. Then is declared a joyful prospect of all good when God shall do this. The success of the gospel brings outward mercies with it; righteousness exalts a nation. The blessing of the Lord sweetens all our creature-comforts to us, and makes them comforts indeed. All the world shall be brought to worship Him. When the gospel begins to spread, it shall go forward more and more, till it reaches to the ends of the earth. It is good to cast in our lot with those that are the blessed of the Lord. If nothing had been spoken in Scripture respecting the conversion of the heathen, we might think it vain to attempt so hopeless a work. But when we see with what confidence it is declared in the Scriptures, we may engage in missionary labours, assured that God will fulfil his own word. And shall we be backward to make known to the heathen the knowledge with which we are favoured, and the salvation we profess to glory in? They cannot learn unless they are taught. Then let us go forward in the strength of the Lord, and look to him to accompany the word the Holy Ghost; then Satan's kingdom shall be destroyed, and the kingdom of our Redeemer established.Commentary by Matthew Henry, 1710.
