'Alarm' in the Bible

My bowels, my bowels! I writhe! The walls of my heart! My heart is restless within me, I cannot keep silent, for I hear [in] my inner self the sound of a horn, [the] alarm of war.

And let that man be like the cities that Yahweh demolished without regret, and let him hear a cry for help in the morning, and an alarm at the time of noon.

{And then}, the moment of their hearing all the words, {they turned to one another in alarm} and they said to Baruch, "We must certainly report all these words to the king!"

{Therefore} look, days [are] coming," {declares} Yahweh, "and I will sound against Rabbah, the {Ammonites}, [the] alarm of [the] war, and it will become as a mound of desolation, and its daughters will burn in the fire. Then Israel will dispossess his dispossessors," says Yahweh.
