26 O give thanks unto the God of heaven: for his mercy endureth for ever.

27 O give thanks unto the Lord of lords: for his mercy endureth for ever.

PSALM 137. Super flumina.

By the waters of Babylon we sat down and wept: when we remembered thee, O Sion.

2 As for our harps, we hanged them up: upon the trees that are therein.

3 For they that led us away captive required of us then a song, and melody in our heaviness: Sing us one of the songs of Sion.

4 How shall we sing the Lord's song: in a strange land?

5 If I forget thee, O Jerusalem: let my right hand forget her cunning.

6 If I do not remember thee, let my tongue cleave to the roof of my mouth: yea, if I prefer not Jerusalem in my mirth.

7 Remember the children of Edom, O Lord, in the day of Jerusalem: how they said, Down with it, down with it, even to the ground.
