7And some fell among thorns; and the thorns sprung up, and choked them:

8But other fell into good ground, and brought forth fruit, some an hundredfold, some sixtyfold, some thirtyfold.

9Who hath ears to hear, let him hear.

10And the disciples came, and said unto him, Why speakest thou unto them in parables?
