Deuteronomy 31:25

23He commissioned Joshua the son of Nun, and said, “Be strong and courageous; for you shall bring the children of Israel into the land which I swore to them. I will be with you.”

24When Moses had finished writing the words of this law in a book, until they were finished,

25Moses commanded the Levites, who bore the ark of the LORD’s covenant, saying,

26“Take this book of the law, and put it by the side of the ark of the LORD your God’s covenant, that it may be there for a witness against you.

27For I know your rebellion and your stiff neck. Behold, while I am yet alive with you today, you have been rebellious against the LORD. How much more after my death?
