'Fall' in the Bible

Also anything on which one of them falls after dying becomes unclean, whether it is an article of wood or clothing, or a skin, or a sack—any article that is used—it must be put in water, and will be unclean until the evening; then it becomes clean.

‘Do not profane your daughter by making her a prostitute, so that the land will not fall to prostitution and become full of wickedness.

And you will chase your enemies, and they will fall before you by the sword.

Five of you will chase a hundred, and a hundred of you will put ten thousand to flight; your enemies will fall before you by the sword.

As for those who are left of you, I will bring despair (lack of courage, weakness) into their hearts in the lands of their enemies; the sound of a scattered leaf will put them to flight, and they will flee as if [running] from the sword, and will fall even when no one is chasing them.
