Joshua 23:7-13

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. “The LORD has forced many great and powerful nations to leave ahead of you. No nation has been able to defeat you. With his help, one Israelite could defeat a thousand, because the LORD your God fights for you, as he promised to do. So you must be careful to love the LORD your God. “If you turn away from the way of the LORD and become friends with these people who are not part of Israel and marry them, the LORD your God will not help you defeat your enemies. They will be like traps for you, like whips on your back and thorns in your eyes, and none of you will be left in this good land the LORD your God has given you.
