The New Century Hymnal‎ #10

1 Rock of ages, let our song
praise your saving power;
you, amid the raging foe,
were our sheltering tower.
Furious it assailed us,
but your arm availed us,
and your word broke its sword
when our own strength failed us.

2 Children of the Holy God,
whether free or fettered,
wake the echoes of that song
where you may be scattered.
Yours the message cheering
that the time is nearing
which will see all set free,
tyrants no more fearing.

Hebrew -
1 Maoz tsur y'shuati l'cha naeh l'shabeiach,
tikon beit t'filati v'sham todah n'zabeiach.
L'eit tachin matbeiach mitzar ham'nabeiach,
az egmor b'shir mizmor chanakat hamiz beiach.
