Joshua 23:9-13

For the Lord has driven out great and mighty nations from before you; and as for you, no one has stood against you to this day.

One of your men puts to flight a thousand, for the Lord your God is He who fights for you, just as He promised you.

So take great care for yourselves that you love the Lord your God.

For if you ever go back and cling to the rest of these nations, these which remain with you, and intermarry with them, so that you associate with them and they with you,

know with certainty that the Lord your God will not continue to drive these nations out from before you; but they will be a snare and a trap to you, and a whip on your sides and thorns in your eyes, until you perish from this good land which the Lord your God has given you.
