Luke 6:45

45 A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. What you say flows from what is in your heart.

Luke 6:45 Meaning and Commentary

Luke 6:45

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).

44 A tree is identified by its fruit. Figs are never gathered from thornbushes, and grapes are not picked from bramble bushes.

45 A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart. What you say flows from what is in your heart.

46 “So why do you keep calling me ‘Lord, Lord!’ when you don’t do what I say?

47 I will show you what it’s like when someone comes to me, listens to my teaching, and then follows it.
