Jesus had performed His first miracle and he had driven out deceptive money makers from God’s house. The people were trusting Him but He didn’t trust them.

John 2:

23 Because of the miraculous signs Jesus did in Jerusalem at the Passover celebration, many began to trust in him. 24 But Jesus didn’t trust them, because he knew all about people. 25 No one needed to tell him about human nature, for he knew what was in each person’s heart.
