'Have No Knowledge' in the Bible

But to you I say, to the rest in Thyatira, even to those who have not this teaching, and have no knowledge of the secrets of Satan, as they say; I put on you no other weight.

Keep in mind, then, the teaching which was given to you, and be ruled by it and have a change of heart. If then you do not keep watch, I will come like a thief, and you will have no knowledge of the hour when I will come on you.
