'Signal' in the Bible

“Run for safety, you children of Benjamin,Out of the midst of Jerusalem!And blow a trumpet in Tekoa [in Judah]And raise a signal-fire in Beth-haccherem [near Jerusalem];For evil is looking down [with eager anticipation] from the north,And great destruction.

“Declare among the nations.Lift up a signal [to spread the news]—publish and proclaim it,Do not conceal it; say,‘Babylon has been taken,Bel [the patron god] has been shamed, Marduk (Bel) has been shattered.Babylon’s images have been shamed, her [worthless] idols have been thrown down.’

Set up a signal on the walls of Babylon [to spread the news];Post a strong blockade,Station the guards,Prepare the men for ambush!For the Lord has both purposed and doneThat which He spoke against the people of Babylon.

Lift up a signal in the land [to spread the news]!Blow the trumpet among the nations!Dedicate the nations [for war] against her;Call against her the kingdoms of Ararat, Minni, and Ashkenaz.Appoint a marshal against her;Cause the horses to come up like bristly locusts [with their wings not yet released from their cases].
