Ephesians 4 NKJV
29 Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. 30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. 31 Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. 32 And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you.

1 Timothy 4:7

1 Timothy 6:20
[ Guard the Faith ] O Timothy! Guard what was committed to your trust, avoiding the profane and idle babblings and contradictions of what is falsely called knowledge—
2 Timothy 2:16
But shun profane and idle babblings, for they will increase to more ungodliness.
Hebrews 12:16
lest there be any fornicator or profane person like Esau, who for one morsel of food sold his birthright.
Profane in the above contexts refers to being "sinful".
