Joshua 4:10 - Ellicott's Commentary On The Whole Bible

According to all that Moses commanded Joshua. — It would seem that the passage of Jordan had been made the subject of some directions by Moses, though nothing is written concerning the manner of it in the Pentateuch. It is noticeable that if Israel had gone into the land when Moses brought them to the frontier at Kadesh-barnea, in the second year of the Exodus, they would have had no occasion to pass the Jordan at all. When the route was changed we cannot say, unless the compassing of the land of Edom (Numbers 21), when they left Kadesh the second time, because they were not permitted to cross that territory, marks the decision. If so, the fact suggests some interesting reflections.
