29 Because of your temple at Jerusalem,
kings shall bring presents to you. 30 Rebuke the wild animal of the reeds,
the multitude of the bulls, with the calves of the peoples.
Being humbled, may it bring bars of silver.
Scatter the nations that delight in war. 31 Princes shall come out of Egypt.
Ethiopia shall hurry to stretch out her hands to God.

32 Sing to God, you kingdoms of the earth!
Sing praises to the Lord! Selah. 33 To him who rides on the heaven of heavens, which are of old;
behold, he utters his voice, a mighty voice. 34 Ascribe strength to God!
His excellency is over Israel,
his strength 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.
