Joshua 13:1 - Joseph Benson’s Commentary on the Old and New Testaments

Now Joshua was old To what age Joshua was advanced we cannot determine, because we do not know how old he was when the Israelites came out of Egypt. Some think he was three and forty at that time, and then he was fourscore and three when they came into Canaan. And now, it may be gathered from probable conjectures, that he wanted not much of a hundred. And, in this declining age, he could not hope to live to conquer what remained of the land unsubdued, and therefore he was to go about another business, namely, the dividing of it. The Lord said unto him, Thou art old Therefore delay not to do the work which I have commanded thee to do. It is good for those that are stricken in years to be reminded that they are so; that they may be quickened to do the work of life, and prepare for death, which is coming on apace.
