Bible Verses About Protection: Backsliding

“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.

Yet you have forsaken me, and served other gods: therefore I will save you no more.
