2 Timothy 3:16-17
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work.

1 Timothy 5:8 But if anyone does not provide for his relatives, and especially for members of his household, he has denied the faith and is worse than an unbeliever.

2 Corinthians 6:14-18 Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness? What accord has Christ with Belial? Or what portion does a believer share with an unbeliever? What agreement has the temple of God with idols? For we are the temple of the living God; as God said, “I will make my dwelling among them and walk among them, and I will be their God, and they shall be my people. Therefore go out from their midst, and be separate from them, says the Lord, and touch no unclean thing; then I will welcome you, and I will be a father to you, and you shall be sons and daughters to me, says the Lord Almighty.”

1 Corinthians 5:9-13
I wrote to you in my letter not to associate with sexually immoral people— not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? God judges those outside. “Purge the evil person from among you.”

Galatians 1:8-9
But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.

John 14:26
But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.

John 14:15
“If you love me, you will keep my commandments.”

Matthew 5:19
Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven.

Matthew 4:7
Jesus said to him, “Again it is written, ‘You shall not put the Lord your God to the test.’”

Jeremiah 17:10 “I the Lord search the heart and test the mind, to give every man according to his ways, according to the fruit of his deeds.”

Jeremiah 17:9
The heart is deceitful above all things, and desperately sick; who can understand it?

Deuteronomy 28:47-48
Because you did not serve the Lord your God with joyfulness and gladness of heart, because of the abundance of all things, therefore you shall serve your enemies whom the Lord will send against you, in hunger and thirst, in nakedness, and lacking everything. And he will put a yoke of iron on your neck until he has destroyed you.

Deuteronomy 28:1-68
“And if you faithfully obey the voice of the Lord your God, being careful to do all his commandments that I command you today, the Lord your God will set you high above all the nations of the earth.” And all these blessings shall come upon you and overtake you, if you obey the voice of the Lord your God. Blessed shall you be in the city, and blessed shall you be in the field. Blessed shall be the fruit of your womb and the fruit of your ground and the fruit of your cattle, the increase of your herds and the young of your flock. Blessed shall be your basket and your kneading bowl. …
