(lie in) ambush(-ment), lay (lie in) wait

Concise Bible Dictionary:

A stratagem used in war of placing warriors in secret places, from which they can issue forth when least expected. Palestine with its many ravines and caves was well suited for such tactics. (Josh. 8:2-222And thou shalt do to Ai and her king as thou didst unto Jericho and her king: only the spoil thereof, and the cattle thereof, shall ye take for a prey unto yourselves: lay thee an ambush for the city behind it. 3So Joshua arose, and all the people of war, to go up against Ai: and Joshua chose out thirty thousand mighty men of valor, and sent them away by night. 4And he commanded them, saying, Behold, ye shall lie in wait against the city, even behind the city: go not very far from the city, but be ye all ready: 5And I, and all the people that are with me, will approach unto the city: and it shall come to pass, when they come out against us, as at the first, that we will flee before them, 6(For they will come out after us) till we have drawn them from the city; for they will say, They flee before us, as at the first: therefore we will flee before them. 7Then ye shall rise up from the ambush, and seize upon the city: for the Lord your God will deliver it into your hand. 8And it shall be, when ye have taken the city, that ye shall set the city on fire: according to the commandment of the Lord shall ye do. See, I have commanded you. 9Joshua therefore sent them forth: and they went to lie in ambush, and abode between Beth-el and Ai, on the west side of Ai: but Joshua lodged that night among the people. 10And Joshua rose up early in the morning, and numbered the people, and went up, he and the elders of Israel, before the people to Ai. 11And all the people, even the people of war that were with him, went up, and drew nigh, and came before the city, and pitched on the north side of Ai: now there was a valley between them and Ai. 12And he took about five thousand men, and set them to lie in ambush between Beth-el and Ai, on the west side of the city. 13And when they had set the people, even all the host that was on the north of the city, and their liers in wait on the west of the city, Joshua went that night into the midst of the valley. 14And it came to pass, when the king of Ai saw it, that they hasted and rose up early, and the men of the city went out against Israel to battle, he and all his people, at a time appointed, before the plain; but he wist not that there were liers in ambush against him behind the city. 15And Joshua and all Israel made as if they were beaten before them, and fled by the way of the wilderness. 16And all the people that were in Ai were called together to pursue after them: and they pursued after Joshua, and were drawn away from the city. 17And there was not a man left in Ai or Beth-el, that went not out after Israel: and they left the city open, and pursued after Israel. 18And the Lord said unto Joshua, Stretch out the spear that is in thy hand toward Ai; for I will give it into thine hand. And Joshua stretched out the spear that he had in his hand toward the city. 19And the ambush arose quickly out of their place, and they ran as soon as he had stretched out his hand: and they entered into the city, and took it, and hasted and set the city on fire. 20And when the men of Ai looked behind them, they saw, and, behold, the smoke of the city ascended up to heaven, and they had no power to flee this way or that way: and the people that fled to the wilderness turned back upon the pursuers. 21And when Joshua and all Israel saw that the ambush had taken the city, and that the smoke of the city ascended, then they turned again, and slew the men of Ai. 22And the other issued out of the city against them; so they were in the midst of Israel, some on this side, and some on that side: and they smote them, so that they let none of them remain or escape. (Joshua 8:2‑22); 2 Chron. 13:1313But Jeroboam caused an ambushment to come about behind them: so they were before Judah, and the ambushment was behind them. (2 Chronicles 13:13); 2 Chron. 20:2222And when they began to sing and to praise, the Lord set ambushments against the children of Ammon, Moab, and mount Seir, which were come against Judah; and they were smitten. (2 Chronicles 20:22); Jer. 51:1212Set up the standard upon the walls of Babylon, make the watch strong, set up the watchmen, prepare the ambushes: for the Lord hath both devised and done that which he spake against the inhabitants of Babylon. (Jeremiah 51:12)).
