“Now after the death of Moses the servant of the LORD it came to pass, that the LORD spake unto Joshua the son of Nun, Moses' minister, saying,”
King James Version (KJV)
Matthew Henry's Concise Commentary
1:1-4 Joshua had attended upon Moses. He who was called to honour, had been long used to business. Our Lord Jesus took upon him the form of a servant. Joshua was trained up under command. Those are fittest to rule, who have learned to obey. The removal of useful men should quicken survivors to be the more diligent in doing good. Arise, go over 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, having ordered the people over, would open a way.
“And when they had brought their ships to land, they forsook all, and followed him.”
