(45) A good man out of the good treasure.--See Note on Matthew 12:35. There the words are spoken in immediate connection with the judgment which the Pharisees had passed on our Lord as casting out devils by Beelzebub, and follow on a reproduction of the similitude of the tree and its fruit. The sequence of thought in that passage helps us to trace a like sequence here. Out of the "good treasure of his heart" the good man would bring forth, not harsh or hasty judgment, but kindness, gentleness, compassion; out of the "evil treasure" the man who was evil, the hypocrite who judged others by himself, would bring forth bitterness, and harsh surmises, and uncharitable condemnation.

6:37-49 All these sayings Christ often used; it was easy to apply them. We ought to be very careful when we blame others; for we need allowance ourselves. If we are of a giving and a forgiving spirit, we shall ourselves reap the benefit. Though full and exact returns are made in another world, not in this world, yet Providence does what should encourage us in doing good. Those who follow the multitude to do evil, follow in the broad way that leads to destruction. The tree is known by its fruits; may the word of Christ be so grafted in our hearts, that we may be fruitful in every good word and work. And what the mouth commonly speaks, generally agrees with what is most in the heart. Those only make sure work for their souls and eternity, and take the course that will profit in a trying time, who think, speak, and act according to the words of Christ. Those who take pains in religion, found their hope upon Christ, who is the Rock of Ages, and other foundation can no man lay. In death and judgment they are safe, being kept by the power of Christ through faith unto salvation, and they shall never perish.A good man out of the good treasure of his heart,.... This, because of its suitableness and agreement with what goes before, is placed by Luke here; though, according to Matthew, it was spoken at another time and place, unless it should be a repetition there; See Gill on Matthew 12:35.

for of the abundance of the heart his mouth speaketh. The Vulgate Latin, Arabic, Ethiopic, Syriac, and Persic versions, leave out the word "his"; and the two latter read "lips", instead of "mouth"; See Gill on Matthew 12:34.
