If I Forget Thee, Jerusalem

If I forget thee, Jerusalem,
Then let my right be forgotten.
Let my right be forgotten, and my left remember.
Let my left remember, and your right close
And your mouth open near the gate.
I shall remember Jerusalem
And forget the forest,    my love will remember,
Will open her hair, will close my window,
will forget my right,
Will forget my left.
If the west wind does not come
I'll never forgive the walls,
Or the sea, or myself.
Should my right forget
My left shall forgive,
I shall forget all water,
I shall forget my mother.
If I forget thee, Jerusalem,
Let my blood be forgotten.
I shall touch your forehead,
Forget my own,
My voice change
For the second and last time
To the most terrible of voices,
Or silence.
