'Pursuers' in the Bible

So the men chased after them on {the way to the Jordan} at the fords; and they shut the gate behind the pursuers that had gone out after them.

And she said to them, "Go to the mountain, so that the pursuers will not find you, and hide yourselves there three days until the pursuers return, and afterward you may go {on your way}."

They departed and came to the mountain, and they stayed there three days until the pursuers returned. The pursuers searched {all along the way} but did not find [them].

Then the men of Ai looked behind them, and they saw smoke from the city rising to the sky; {they had no power to flee this way or that}, and the people fleeing the wilderness turned around to the pursuers.
