John Gill's Bible Commentary Ver. 3. Every place that the sole of your feet shall tread upon , etc.] That is, in the land of Canaan: that have I given unto you, as I said unto Moses : (see Gill on “ Deuteronomy 11:24”); though the Jews extend this to all without the land subdued by them, and even to all the countries they now tread on, and are exiles in; but the limits of what the Lord gave them are fixed in ( Joshua 1:4).
Matthew Henry Commentary
Verses 1-4 - Joshua had attended upon Moses. He who was called to honour, had bee long used to business. Our Lord Jesus took upon him the form of servant. Joshua was trained up under command. Those are fittest to rule, who have learned to obey. The removal of useful men shoul quicken survivors to be the more diligent in doing good. Arise, go ove Jordan. At this place and at this time the banks were overflowed Joshua had no bridge or boats, and yet he must believe that God, havin ordered the people over, would open a way.
