Theodore Beza
47:1 [To the chief Musician, A Psalm for the sons of Korah.] O {a} clap your hands, all ye people; shout unto God with the voice of triumph.
(a) Here is figured Christ to whom all his should give willing obedience, and who would show himself terrible to the wicked.
47:3 He shall {b} subdue the people under us, and the nations under our feet.
(b) He has made the Jews who were the keepers of the law and prophets, schoolmasters to the Gentiles, that they would with gladness obey them.
47:4 He shall choose {c} our inheritance for us, the excellency of Jacob whom he loved. Selah.
(c) God has chosen us above all other nations, to enjoy a most glorious inheritance.
47:5 God is gone up with a shout, the LORD with the {d} sound of a trumpet.
(d) He alludes to the trumpets that were blown at solemn feasts: but he further signifies the triumph of Christ and his glorious ascension into the heavens.
47:7 For God [is] the King of all the earth: sing ye praises with {e} understanding.
(e) He requires that understanding be joined with singing, lest the Name of God be profaned with vain crying.
47:9 The princes of the people are gathered together, [even] the people of the God of Abraham: for the shields of the earth [belong] unto God: he {f} is greatly exalted.
(f) He praises God’s highness, for that he joins the great princes of the world
(whom he calls shields) to the fellowship of his Church.
