The next matter in Psalm 68 is the spreading from the temple into the city of God.
"Strengthen, O God, that which You have done for us. / Because of Your temple at Jerusalem" (vv. 28b-29a). This word indicates that following God's strengthening of what He has done for His elect, the influence of the enjoyment of God in His house would spread to the entire city of Jerusalem because of the house of God, which was at Jerusalem.
The house of God signifies the local church, and the city of Jerusalem signifies the kingdom, the strengthening and the safeguard of the church.
Psalm 68 concludes with a word about the gaining of the earth for God (vv. 29b-35).
The influence of the enjoyment of God will gain the whole earth for God.
According to verse 29b, kings of the nations will bring a gift to God.
God will deal with the Egyptians, who are likened to animals in the reeds by the Nile (v. 30a).
God will also deal with the nations, who are likened to herds of the bulls among the calves and who lust for silver and delight in war (v. 30b).
