4 How shall we sing the song of the Lord in the land of strangers?
5 If I forget thee, O Jerusalem, my right hand shall be forgotten.
6 If I do not remember thee, my tongue shall cleave to the roof of my mouth; if I do not prefer to lift up Jerusalem as my chief joy.
7 Remember, O Lord, the sons of Edom in the day of Jerusalem; who said, Raze it, raze it, even to the foundation thereof.
8 O daughter of Babylon, who art to be destroyed; happy shall he be, that rewards thee as thou hast served us.
9 Happy shall he be, that takes and dashes thy offspring against the stones.
