Joshua 23:4-8

4See, I have allotted as an inheritance to your tribes these remaining nations, including all the nations I have already cut off, from the Jordan westward to the Great Sea.1 5The LORD your God will push them out of your way and drive them out before you, so that you can take possession of their land, as the LORD your God promised you.

6Be very strong, then, so that you can keep and obey all that is written in the Book of the Law of Moses, not turning aside from it to the right or to the left. 7So you are not to associate with these nations that remain among you. You must not call on the names of their gods or swear by them, and you must not serve them or bow down to them. 8Instead, you shall hold fast to the LORD your God, as you have done to this day.
