Joshua 23:6-13

61Be very firm, then, to keep and do all that is written in the book of the law of Moses, so that you may not turn aside from it to the right hand or to the left, 7so that you will not 2associate with these nations, these which remain among you, or 3mention the name of their gods, or 4make anyone swear by them, or 5serve them, or bow down to them. 8But you are to cling to the Lord your God, as you have done to this day. 96For the Lord has 7driven out great and strong nations from before you; and as for you, 8no man has stood before you to this day. 109One of your men puts to flight a thousand, for the Lord your God is 10He who fights for you, just as He 11promised you. 11So take diligent heed to yourselves to love the Lord your God. 12For if you ever go back and 12cling to the rest of these nations, these which remain among you, and 13intermarry with them, so that you 14associate with them and they with you, 13know with certainty that the Lord your God will not continue to 15drive these nations out from before you; but they will be a 16snare and a trap to you, and a whip on your sides and thorns in your eyes, until you perish from off this good land which the Lord your God has given you.
