Joshua 8:29

And the king of Ai he hanged on a tree. — (See Note on Deuteronomy 21:22.) Heb., on the tree. Why “the tree”? It would appear from Joshua 8:2; Joshua 10:1, that the king of Jericho was also hanged; possibly both were hanged on the same tree, and were exhibited, each in turn, as “the curse of God.” But when we read of this treatment of the enemies of Joshua, we cannot but be reminded of the greater Joshua, who fulfilled the curse of God in His own person, and made a show of the “principalities and powers” by triumphing over them in His cross. (Comp. also Esther 9:10; Esther 9:13.)

Jericho and Ai are the only cities of Canaan of which the capture by Joshua is recorded in detail. Their capture stands in the narrative, as it was in fact, a specimen of the whole conquest of the Canaanite cities. Two campaigns in like manner are recorded as specimens of Joshua’s battles with the enemy in the open field. In the capture of Jericho and in the southern campaign, the hand of God is more especially manifested. In the capture of Ai and in the northern campaign, the labour of Israel in the conflict is more prominent. The whole work is thus presented to us in a twofold aspect, as the work of Israel and the work of God.

A great heap of stones. — Not only the death, but the burial of the king of Ai is recorded, as also the burial of the five kings in Joshua 10:27. The same thing was done to Achan (Joshua 7:26), and to Absalom (2 Samuel 18:17). This kind of burial is another form of the curse, and is a fitting sequel to the hanging of the body upon the tree.
