'Knew' in the Bible

Then He cured numbers of people who were ill with various diseases, and He drove out many demons; not allowing the demons to speak, because they knew who He was.

But the people saw them going, and many knew them; and coming by land they ran together there from all the neighbouring towns, and arrived before them.

For he knew not what to say: they were filled with such awe.

Then one of the Scribes, who had heard them disputing and well knew that Jesus had given them an answer to the point, and a forcible one, came forward and asked Him, "Which is the chief of all the Commandments?"

When He returned He again found them asleep, for they were very tired; and they knew not how to answer Him.
