Psalm 119:102

I have not turned aside from Your ordinances,
For You Yourself have taught me.

Psalm 18:21

For I have kept the ways of the Lord,
And have not wickedly departed from my God.

Proverbs 5:7

Now then, my sons, listen to me
And do not depart from (forget) the words of my mouth.

I will make an everlasting covenant with them that I will do them good and not turn away from them; and I will put in their heart a fear and reverential awe of Me, so that they will not turn away from Me.

Ephesians 4:20-24

But you did not learn Christ in this way!

1 Thessalonians 2:13

And we also thank God continually for this, that when you received the word of God [concerning salvation] which you heard from us, you welcomed it not as the word of [mere] men, but as it truly is, the word of God, which is effectually at work in you who believe [exercising its inherent, supernatural power in those of faith].

1 John 2:19

They went out from us [seeming at first to be Christians], but they were not really of us [because they were not truly born again and spiritually transformed]; for if they had been of us, they would have remained with us; but they went out [teaching false doctrine], so that it would be clearly shown that none of them are of us.

1 John 2:27

As for you, the anointing [the special gift, the preparation] which you received from Him remains [permanently] in you, and you have no need for anyone to teach you. But just as His anointing teaches you [giving you insight through the presence of the Holy Spirit] about all things, and is true and is not a lie, and just as His anointing has taught you, you must remain in Him [being rooted in Him, knit to Him].
