This chapter is a summary of Israel's conquests. I. Their conquests under Moses, on the other side Jordan (for we now suppose ourselves in Canaan) eastward, which we had the history of, Num 21:24, etc. And here the abridgment of that history (Jos 12:1-6). II. Their conquests under Joshua, on this side Jordan, westward. 1. The country they reduced (Jos 12:7, Jos 12:8). 2. The kings they subdued, thirty-one in all (v. 9-24). And this comes in here, not only as a conclusion of the history of the wars of Canaan (that we might at one view see what they had got), but as a preface to the history of the dividing of Canaan, that all that might be put together which they were not to make a distribution of.
