Jeremiah 46:21-22

Also her hired men {are} in the midst of her like fatted bullocks; for they also are turned back, {and} are fled away together: they did not stand, because the day of their calamity was come upon them, {and} the time of their visitation. {fatted...: Heb. bullocks of the stall} The voice thereof shall go like a serpent; for they shall march with an army, and come against her with axes, as hewers of wood.
