Darby's Bible Synopsis
Psalm 47 only pursues this deliverance to its bright results for Israel according to God's glory in the earth. Jehovah is now a great King over all the earth (compare Zechariah 14). He subdues the nations under Israel and Himself chooses their inheritance. This is triumphantly celebrated from Verses 5-9 (Psalm 47:5-9), and the association of the princes of the peoples now owning God, with the people of the God of Abraham. He is specially Israel's (the remnant's) King, but if He is, He is King of all the earth. In these Verses God Himself is celebrated, but He is the God of Israel. It is the celebration of the earthly part of the millennial glory of God: Israel owned in the delivered remnant being the center. I apprehend Verse 9 (Psalm 47:9) should be "have joined themselves to the people."
For the LORD most high is terrible; he is a great King over all the earth.
He shall subdue the people under us, and the nations under our feet.
He shall choose our inheritance for us, the excellency of Jacob whom he loved. Selah.
God is gone up with a shout, the LORD with the sound of a trumpet.
Sing praises to God, sing praises: sing praises unto our King, sing praises.
For God is the King of all the earth: sing ye praises with understanding.
God reigneth over the heathen: God sitteth upon the throne of his holiness.
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 is greatly exalted.
