He knows your heart

Jesus did not entrust himself to them, because he knew what was in them. (John 2:23-25)

To put it in context, today’s passage comes after Jesus is announced by John and calls his first disciples (John 1), and immediately after the miracle at Cana and the cleansing of the temple (John 2). Jesus is in Jerusalem for the Passover and many people are responding to his ministry. But the passage says that Jesus did not entrust himself to them.
