Context Reading
23Then the LORD commissioned Joshua son of Nun and said, “Be strong and courageous, for you will bring the Israelites into the land that I swore to give them, and I will be with you.” 24When Moses had finished writing in a book the words of this law from beginning to end, 25he gave this command to the Levites who carried the ark of the covenant of the LORD: 26“Take this Book of the Law and place it beside the ark of the covenant of the LORD your God, so that it may remain there as a witness against you. 27For I know how rebellious and stiff-necked you are. If you are already rebelling against the LORD while I am still alive, how much more will you rebel after my death!
