Lift up your heads, O gates

Father Justin pounds on the church door with the cross as he shouts the following verses:
Lift up your heads, O gates,
and be lifted up, O ancient doors!
that the King of glory may come in.

Who is the King of glory?
The Lord strong and mighty.
The Lord mighty in battle.

Lift up your heads, O gates,
and lift them up, O ancient doors!
that the King of glory may come in!

Who is this King of glory?
The Lord of hosts,
he is the King of glory (Psalm 24:7-10).
