Luke 11:24 When an evil spirit comes out of a man, it goes through arid places seeking rest and does not find it. Then it says, ‘I will return to the house I left.’ (25) When it arrives, it finds the house swept clean and put in order. (26) Then it goes and takes seven other spirits more wicked than itself, and they go in and live there. And the final condition of that man is worse than the first.
Hebrews 10:26 If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, (27) but only a fearful expectation of judgment and of raging fire that will consume the enemies of God.
Joshua 23:12 But if you turn away and ally yourselves with the survivors of these nations that remain among you and if you intermarry with them and associate with them, (13) then you may be sure that the LORD your God will no longer drive out these nations before you. Instead, they will become snares and traps for you, whips on your backs and thorns in your eyes, until you perish from this good land, which the LORD your God has given you.
Judges 2:1 . . . I said, I will never break my covenant with you, (2) and you shall not make a covenant with the people of this land, but you shall break down their altars. Yet you have disobeyed me. . . . (3) Now therefore I tell you that I will not drive them out before you; they will be [thorns] in your sides and their gods will be a snare to you.
Judges 2:20 Therefore the LORD was very angry with Israel and said, Because this nation has violated the covenant that I laid down for their forefathers and has not listened to me, (21) I will no longer drive out before them any of the nations Joshua left when he died. (22) I will use them to test Israel and see whether they will keep the way of the LORD and walk in it as their forefathers did. (23) The LORD had allowed those nations to remain; he did not drive them out at once by giving them into the hands of Joshua. (3:1) These are the nations the LORD left to test all those Israelites who had not experienced any of the wars in Canaan . . . (4) They were left to test the Israelites to see whether they would obey the LORD’s commands, which he had given their forefathers through Moses.
