Joshua 1:7

1:7 Make sure you are very strong and brave! Carefully obey all the law my servant Moses charged you to keep! Do not swerve from it to the right or to the left, so that you may be successful in all you do.

Joshua 8:31

8:31 just as Moses the Lord’s servant had commanded the Israelites. As described in the law scroll of Moses, it was made with uncut stones untouched by an iron tool. They offered burnt sacrifices on it and sacrificed tokens of peace.
