Moses being dead, the Lord directs and encourages Joshua to take the command of the children of Israel, and go over Jordan with them, and take possession of the land of Canaan, and divide it to them; giving him gracious promises and strong assurances of his presence, and some good advice with respect to his conduct, Jos 1:1; upon which Joshua orders the people to be ready in three days to go along with him, Jos 1:10; and particularly addresses the Reubenites and Gadites, and half tribe of Manasseh, and puts them in mind of what Moses had ordered, and they had promised, to go along with their brethren, and assist them in conquering the land, Jos 1:12; which they readily agreed to do, and promised obedience to him in all things, Jos 1:16.
