Nineveh is like a pool whose water is draining away. "Stop! Stop!" they cry, but no one turns back. (NIV)
And Nineveh, like a standing pool are her waters and [her inhabitants] are fleeing away! Stand! Stand [firm! a few cry], but no one looks back or causes them to return. (AMP)
But Nineveh is of old like a pool of water: yet they shall flee away. Stand, stand, shall they cry; but none shall look back. (KJV)
