4:17 From that time on Jesus began to preach, “Repent, for the kingdom of heaven has come near.”

… 5: 1 Now when Jesus saw the crowds, he went up on a mountainside and sat down. His disciples came to him, 2 and he began to teach them.

… 7:24 “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”

28 When Jesus had finished saying these things, the crowds were amazed at his teaching, 29 because he taught as one who had authority, and not as their teachers of the law.
