Josh 23:4-13

4I have allotted to you as an inheritance for your tribes those nations that remain, along with all the nations that I have already cut off, from the Jordan to the Great Sea in the west.5The Lord your God will push them back before you, and drive them out of your sight; and you shall possess their land, as the Lord your God promised you.6Therefore be very steadfast to observe and do all that is written in the book of the law of Moses, turning aside from it neither to the right nor to the left,7so that you may not be mixed with these nations left here among you, or make mention of the names of their gods, or swear by them, or serve them, or bow yourselves down to them,8but hold fast to the Lord your God, as you have done to this day.9For the Lord has driven out before you great and strong nations; and as for you, no one has been able to withstand you to this day.10One of you puts to flight a thousand, since it is the Lord your God who fights for you, as he promised you.11Be very careful, therefore, to love the Lord your God.12For if you turn back, and join the survivors of these nations left here among you, and intermarry with them, so that you marry their women and they yours,13know assuredly that the Lord your God will not continue to drive out these nations before you; but they shall be a snare and a trap for you, a scourge on your sides, and thorns in your eyes, until you perish from this good land that the Lord your God has given you.
