1 Timothy 1:3-4
3. As I urged you when I went into Macedonia, stay there in Ephesus so that you may command certain men not to teach false doctrines any longer
4. nor to devote themselves to myths and endless genealogies. These promote controversies rather than God's work--which is by faith.
1 Timothy 1:7
They want to be teachers of the law, but they do not know what they are talking about or what they so confidently affirm.
2 Timothy 4:3-4
3. For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear.
4. They will turn their ears away from the truth and turn aside to myths.
Titus 1:11
They must be silenced, because they are ruining whole households by teaching things they ought not to teach--and that for the sake of dishonest gain.
Titus 2:1
You must teach what is in accord with sound doctrine.
Titus 2:15
These, then, are the things you should teach. Encourage and rebuke with all authority. Do not let anyone despise you.
Hebrews 13:9
Do not be carried away by all kinds of strange teachings.
2 Peter 2:1-3
1. But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them--bringing swift destruction on themselves.
2. Many will follow their shameful ways and will bring the way of truth into disrepute.
3. In their greed these teachers will exploit you with stories they have made up. Their condemnation has long been hanging over them, and their destruction has not been sleeping.
2 John 1:10
If anyone comes to you and does not bring this teaching, do not take him into your house or welcome him.
