Matthew Poole and continuators on Psalms 137:5

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

If I do not retain a deep and sorrowful sence of thy ruine and misery, or if I [illegible: 1+ letters]dulge my self in mirth and jollity, as if I had forgotten thee.

The chief instrument of playing upon musical instruments and of other actions.

i. e. Lose its skill of playing. In the Hebrew it is onely, forget, without expressing what, to intimate the extent and generality of this wish, Let it forget or be disenabled not onely for playing, but for every action in which it was formerly used.
