Ephesians 5:3-4 "But do not let fornication or any impurity or greed even be named among you, as is proper among saints; and there must be no filthiness and foolish-talk, or coarse-jesting, which are not fitting, but rather giving-of-thanks."

Philippians 4:8-9 "Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, let your mind, dwell on these things. The things you have learned and received and heard and seen in me, practice these things; and the God of peace shall be with you."

2 Timothy 3:1-5 "But realize this, that in the last days difficult times will come. For men will be lovers of self, lovers of money, boastful, arrogant, revilers, disobedient to parents, ungrateful, unholy, unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good, treacherous, reckless, conceited, lovers of pleasure rather than lovers of God; holding to a form of godliness, although they have denied its power; and avoid such men as these."

Hebrews 12:14-17 "See to it that no one comes short of the grace of God; that no root of bitterness springing up causes trouble, and by it many be defiled; that there be no fornicator or godless person like Esau, who sold his own birthright for a single meal. For you know that even afterwards, when he desired to inherit the blessing, he was rejected, for he found no place for repentance, though he sought for it with tears."

1 Corinthians 5:6-8 Your boasting is not good. Do you not know that a little leaven leavens the whole lump of dough? Clean out the old leaven, that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed. Let us therefore celebrate the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.

Jude 1:12 These men are those who are hidden reefs in your love feasts when they feast with you without fear, caring for themselves; clouds without water, carried along by winds; autumn trees without fruit, doubly dead, uprooted;
Jude 1:13 wild waves of the sea, casting up their own shame like form; wandering stars, for whom the black darkness has been reserved forever.
Jude 1:14 And about these also Enoch, in the seventh generation from Adam, prophesied, saying, "Behold, the Lord came with many thousands of His holy ones,
Jude 1:15 to execute judgment upon all, and to convict all the ungodly of all their ungodly deeds which they have done in an ungodly way, and of all the harsh things which ungodly sinners have spoken against Him."
Jude 1:16 These are grumblers, finding fault, following after their own lusts; they speak arrogantly, flattering people for the sake of gaining an advantage.
