The Book of Joshua, Chapter 8, Verse 31

And 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.

And 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.

And the king of Ai they took alive, and brought him to Joshua.

And it came to pass, when Israel had made an end of slaying all the inhabitants of Ai in the field, in the wilderness wherein they chased them, and when they were all fallen on the edge of the sword, until they were consumed, that all the Israelites returned unto Ai, and smote it with the edge of the sword.

And [so] it was, [that] all that fell that day, both of men and women, [were] twelve thousand, [even] all the men of Ai.

For Joshua drew not his hand back, wherewith he stretched out the spear, until he had utterly destroyed all the inhabitants of Ai.

Only the cattle and the spoil of that city Israel took for a prey unto themselves, according unto the word of the LORD which he commanded Joshua.

And Joshua burnt Ai, and made it an heap for ever, [even] a desolation unto this day.

And the king of Ai he hanged on a tree until eventide: and as soon as the sun was down, Joshua commanded that they should take his carcase down from the tree, and cast it at the entering of the gate of the city, and raise thereon a great heap of stones, [that remaineth] unto this day.

And he wrote there upon the stones a copy of the law of Moses, which he wrote in the presence of the children of Israel.

And all Israel, and their elders, and officers, and their judges, stood on this side the ark and on that side before the priests the Levites, which bare the ark of the covenant of the LORD, as well the stranger, as he that was born among them; half of them over against mount Gerizim, and half of them over against mount Ebal; as Moses the servant of the LORD had commanded before, that they should bless the people of Israel.

And afterward he read all the words of the law, the blessings and cursings, according to all that is written in the book of the law.

There was not a word of all that Moses commanded, which Joshua read not before all the congregation of Israel, with the women, and the little ones, and the strangers that were conversant among them.

And it came to pass, when all the kings which [were] on this side Jordan, in the hills, and in the valleys, and in all the coasts of the great sea over against Lebanon, the Hittite, and the Amorite, the Canaanite, the Perizzite, the Hivite, and the Jebusite, heard [thereof];

That they gathered themselves together, to fight with Joshua and with Israel, with one accord.

And when the inhabitants of Gibeon heard what Joshua had done unto Jericho and to Ai,

They did work wilily, and went and made as if they had been ambassadors, and took old sacks upon their asses, and wine bottles, old, and rent, and bound up;

And old shoes and clouted upon their feet, and old garments upon them; and all the bread of their provision was dry [and] mouldy.

And they went to Joshua unto the camp at Gilgal, and said unto him, and to the men of Israel, We be come from a far country: now therefore make ye a league with us.
