'Fall' in the Bible

And Solomon said, If he be a worthy man, there shall not one of his hairs fall to the earth; but if wickedness be found in him, he shall die.

And it was told king Solomon that Joab had fled to the tent of Jehovah; and behold, he is by the altar. And Solomon sent Benaiah the son of Jehoiada, saying, Go, fall on him.

And the king said to him, Do as he has said, and fall upon him, and bury him; and take away the innocent blood, which Joab shed, from me and from the house of my father.

and Jehovah said, Who shall entice Ahab that he may go up and fall at Ramoth-Gilead? And one said after this manner, and another said after that manner.
