avoid
Titus 1:14
Not giving heed to Jewish fables, and commandments of men, that turn from the truth.
1 Timothy 1:3-7
3
As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,
4
Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.
5
Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned:
6
From which some having swerved have turned aside unto vain jangling;
7
Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.
1 Timothy 4:7
But refuse profane and old wives' fables, and exercise thyself rather unto godliness.
2 Timothy 2:23
But foolish and unlearned questions avoid, knowing that they do gender strifes.
unprofitable
Job 15:3
Should he reason with unprofitable talk? or with speeches wherewith he can do no good?
1 Corinthians 8:1
Now as touching things offered unto idols, we know that we all have knowledge. Knowledge puffeth up, but charity edifieth.
1 Corinthians 13:2
And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
2 Timothy 2:14
Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers.
