'Watchtower' in the Bible

And Judah hath come in unto the watch-tower, to the wilderness, and they look unto the multitude, and lo, they are carcases fallen to the earth, and there is none escaped,

Arrange the table, watch in the watch-tower, Eat, drink, rise, ye heads, anoint the shield,

And he crieth -- a lion, 'On a watch-tower my lord, I am standing continually by day, And on my ward I am stationed whole nights.

Surely the palace hath been left, The multitude of the city forsaken, Fort and watch-tower hath been for dens unto the age, A joy of wild asses -- a pasture of herds;

A watch-tower I have given thee, Among My people a fortress, And thou knowest, and hast tried their way.

While we exist -- consumed are our eyes for our vain help, In our watch-tower we have watched for a nation that saveth not.
