29 Because of your temple at Jerusalem kings shall bear gifts to you. 30 Rebuke the beasts that dwell among the reeds, the herd of bulls with the calves of the peoples. Trample underfoot those who lust after tribute; scatter the peoples who delight in war.[1] 31 Nobles shall come from Egypt; Cush shall hasten to stretch out her hands to God.

32 O kingdoms of the earth, sing to God; sing praises to the Lord, Selah 33 to him who rides in the heavens, the ancient heavens; behold, he sends out his voice, his mighty voice. 34 Ascribe power to God, whose majesty is over Israel, and whose power is in the skies.

Matthew Henry's Commentary on Psalm 68:29-34

Commentary on Psalm 68:29-31

(Read Psalm 68:29-31)

A powerful invitation is given to those that are without, to join the church. Some shall submit from fear; overcome by their consciences, and the checks of Providence, they are brought to make peace with the church. Others will submit willingly, verses 29,31. There is that beauty and benefit in the service of God, and in the gospel of Christ which went forth from Jerusalem, which is enough to invite sinners out of all nations.

Commentary on Psalm 68:32-35

(Read Psalm 68:32-35)

God is to be admired and adored with reverence and godly fear, by all that attend in his holy places. The God of Israel gives strength and power unto his people. Through Christ strengthening us we can do all things, not otherwise; therefore he must have the glory of all we do, with our humble thanks for enabling us to do it, and for accepting the work of his hands in us.
