The Psalms of David -- Psalm 23

I had no idea where this was until I found it here a while back; I still get flashbacks of my first Pascha when Fr. George banged on the doors of the church from outside and shouted the proclamation below, answering the question asked from inside by one of the men who (quickly) went about changing the candle holders'/cloths' colors while we sang "Thy Resurrection" outside...

⁷ Lift up your heads, O you gates!
And be lifted up, you everlasting doors!
And the King of glory shall come in.

⁸ Who is this King of glory?
The LORD strong and mighty,
The LORD mighty in battle.

⁹ Lift up your heads, O you gates!
Lift up, you everlasting doors!
And the King of glory shall come in.

¹⁰ Who is this King of glory?
The LORD of hosts,
He is the King of glory.

Christ is risen!
