Joshua 23:10

that you not come among these nations, these that remain among you; neither make mention of the name of their gods, nor cause to swear by them, neither serve them, nor bow down yourselves to them;

but hold fast to the LORD your God, as you have done to this day.

“For the LORD has driven great and strong nations out from before you. But as for you, no man has stood before you to this day.

Take good heed therefore to yourselves, that you love the LORD your God.

“But if you do at all go back, and hold fast to the remnant of these nations, even these who remain among you, and make marriages with them, and go in to them, and they to you;

know for a certainty that the LORD your God will no longer drive these nations from out of your sight; but they shall be a snare and a trap to you, a scourge in your sides, and thorns in your eyes, until you perish from off this good land which the LORD your God has given you.
