'Arrow' in the Bible

Jehu aimed his bow and shot an arrow right between Jehoram's shoulders. The arrow went through his heart and he fell to his knees in his chariot.

Elisha said, "Open the east window," and he did so. Elisha said, "Shoot!" and he did so. Elisha said, "This arrow symbolizes the victory the Lord will give you over Syria. You will annihilate Syria in Aphek!"

So this is what the Lord says about the king of Assyria: "He will not enter this city, nor will he shoot an arrow here. He will not attack it with his shield-carrying warriors, nor will he build siege works against it.
