Psalm 24:
Choir: Lift up your heads oh Gates, and be lifted up you eternal Doors, that the King of Glory may enter!
Gate keepers: Who is this king of glory?
Choir: YHWH strong and mighty, YHWH mighty in battle!
Choir: Lift up your heads oh Gates, and be lifted up you eternal Doors, that the King of Glory may enter!
Gate keepers: Who is this king of glory?
Choir: YHWH of hosts, he is the King of Glory!
Where are these gates that are shut tight and refuse to open for the King? I think there is a lot to support the interpretation of the early church fathers that this is a description of the LORD conquering the grave. These gates do not belong to a city or a temple -neither of which had gates that were raised. They are the Eternal Doors (petachi ulam) through which all enter and none leave. I think this makes Psalm 24 one of the most hopeful psalms in the Bible. He is the King of Glory!
