By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion.
We hanged our harps upon the willows in the midst thereof.
For there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion.
How shall we sing the LORD’s song in a strange land?
Psalm 136 (Septuagint, 137 in KJV)
Remembering, therefore, this command of the Savior, and all that came to pass for our sake, the cross, the tomb, the resurrection on the third day, the ascension into heaven, the enthronement at the right hand of the Father, and the second, glorious coming, we offer to You these gifts from Your own gifts in all and for all.
