God has ascended with a shout,
The Lord, with the sound of a trumpet.
Sing praises to God, sing praises;
Sing praises to our King, sing praises.
For God is the King of all the earth;
Sing praises with a skillful psalm.
Psalms 47:5-7

“The 47th psalm is a prophecy of Christ that He shall rise up and become king over all the world, without a battle, simply through shouts, songs, and trumpet calls, that is, through the joyful preaching of the Gospel, just as the walls of Jericho fell by trumpet blasts and shouts, without any weapons at all.”
