The psalmist now turns to the future. First, he prays that God will complete the work which he has begun by continually strengthening Israel (Psalms 68:28). Then he rises to prophecy. Kings and princes shall bring presents to Zion; empires shall prostrate themselves; Egypt and Ethiopia shall hasten to bow down; all the kingdoms of the earth shall ultimately "sing praises unto the Lord."
Israel and the God of Israel will thus be glorified exceedingly.
