'Rear' in the Bible

and thou hast done to Ai and to her king as thou hast done to Jericho and to her king; only, its spoil and its cattle ye spoil for yourselves; set for thee an ambush for the city at its rear.'

and commandeth them, saying, 'See, ye are liers in wait against the city, at the rear of the city, ye go not very far off from the city, and all of you have been prepared,

and they set the people, all the camp which is on the north of the city, and its rear on the west of the city, and Joshua goeth on that night into the midst of the valley.

And it cometh to pass, when the king of Ai seeth it, that hasten, and rise early, and go out do the men of the city to meet Israel for battle, he and all his people, at the appointed season, at the front of the plain, and he hath not known that an ambush is against him, on the rear of the city.

but do not stay there yourselves; pursue your enemies and attack them in the rear. Do not allow them to enter their cities, for the Lord your God has delivered them into your hand.”
