Like watchers of a field they were against her from all around, because she has rebelled against me," {declares} Yahweh.

For I hear the rumor of many, "Terror [is] from all around, denounce [him], yes, let us denounce him!" {All my close friends} [are] watchers of my stumbling, [saying], "perhaps he can be persuaded, and we can prevail over him, and we can take our revenge on him."

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.
