At once, Jesus knew in his spirit what they were saying to themselves. "Why are you arguing about such things among yourselves?" he asked them.

because Herod was afraid of John. He knew that John was a righteous and holy man, and so he protected him. Whenever he listened to John, he did much of what he said. In fact, he liked listening to him.

because he knew that the high priests had handed him over due to jealousy.
