'Teaching' in the Bible

But I have a few [things] against you: that you have there those who hold fast to the teaching of Balaam, who taught Balak to put a stumbling block before the sons of Israel, to eat food sacrificed to idols and to commit sexual immorality.

So likewise you also have those who hold fast to the teaching of the Nicolaitans.

But I say to you, to the rest [who are] in Thyatira, all those who do not hold this teaching, who have not known the deep [things] of Satan, as they say, I do not put upon you any other burden.
