Joshua 23:11-16

Be very careful, therefore, to love the LORD your God. For if you turn back and cling to the remnant of these nations remaining among you and make marriages with them, so that you associate with them and they with you, know for certain that the LORD your God will no longer drive out these nations before you, but they shall be a snare and a trap for you, a whip on your sides and thorns in your eyes, until you perish from off this good ground that the LORD your God has given you. “And now I am about to go the way of all the earth, and you know in your hearts and souls, all of you, that not one word has failed of all the good things that the LORD your God promised concerning you. All have come to pass for you; not one of them has failed. But just as all the good things that the LORD your God promised concerning you have been fulfilled for you, so the LORD will bring upon you all the evil things, until he has destroyed you from off this good land that the LORD your God has given you, if you transgress the covenant of the LORD your God, which he commanded you, and go and serve other gods and bow down to them. Then the anger of the LORD will be kindled against you, and you shall perish quickly from off the good land that he has given to you.”
