13:3 Counted to the Canaanites - That is, which though now possessed by the Philistines, who drove out the Canaanites the old inhabitants of it, Deut 2:23 Amos 9:7, yet is a part of the land of Canaan, and therefore belongs to the Israelites. The Avites - Or, the Avims, as they are called, Deut 2:23, who though they were expelled out of their ancient seat, and most of them destroyed by the Caphtorims or Philistines, as is there said, yet many of them escaped, and planted themselves not very far from the former.
13:1-6 At this chapter begins the account of the dividing of the land of Canaan among the tribes of Israel by lot; a narrative showing the performance of the promise made to the fathers, that this land should be given to the seed of Jacob. We are not to pass over these chapters of hard names as useless. Where God has a mouth to speak, and a hand to write, we should find an ear to hear, and an eye to read; and may God give us a heart to profit! Joshua is supposed to have been about one hundred years old at this time. It is good for those who are old and stricken in years to be put in remembrance of their being so. God considers the frame of his people, and would not have them burdened with work above their strength. And all people, especially old people, should set to do that quickly which must be done before they die, lest death prevent them, Ec 9:10. God promise that he would make the Israelites masters of all the countries yet unsubdued, through Joshua was old, and not able to do it; old, and not likely to live to see it done. Whatever becomes of us, and however we may be laid aside as despised, broken vessels, God will do his own work in his own time. We must work out our salvation, then God will work in us, and work with us; we must resist our spiritual enemies, then God will tread them under our feet; we must go forth to our Christian work and warfare, then God will go forth before us.
