Joshua 23:6-8

“Be strong. You must be careful to obey everything commanded in the Book of the Teachings of Moses. Do not stray from it either from the left or the right. Don’t become friends with the people living among us who are not Israelites. Don’t say the names of their gods or make anyone swear by them. Don’t serve or worship them. You must continue to follow the LORD your God, as you have done in the past.
