'Ambush' in the Bible

A slaughtering arrow is their tongue, Deceit it hath spoken in its mouth, Peace with its neighbour it speaketh, And in its heart it layeth its ambush,

Unto the walls of Babylon lift up an ensign, Strengthen the watch, Establish the watchers, prepare the ambush, For Jehovah hath both devised and done that which He spake, Concerning the inhabitants of Babylon.
