“The good person,

Out of the good treasure

Of his heart,

Produces good.

The evil person,

Out of his evil treasure,

Produces evil.

Out of the abundance

Of the heart,

The mouth speaks.”

ὁ ἀγαθὸς ἄνθρωπος ἐκ τοῦ ἀγαθοῦ θησαυροῦ τῆς καρδίας προφέρει τὸ ἀγαθόν, καὶ ὁ πονηρὸς ἐκ τοῦ πονηροῦ προφέρει τὸ πονηρόν· ἐκ γὰρ περισσεύματος καρδίας λαλεῖ τὸ στόμα αὐτοῦ.

Luke indicated that Jesus continued with his sayings.  The good person (ὁ ἀγαθὸς ἄνθρωπος), out of the good treasure of his heart (ἐκ τοῦ ἀγαθοῦ θησαυροῦ τῆς καρδίας), produces good things (προφέρει τὸ ἀγαθόν).  The evil person (καὶ ὁ πονηρὸς), out of his evil treasure (ἐκ τοῦ πονηροῦ), produces evil (προφέρει τὸ πονηρόν).  Out of the abundance of the heart (ἐκ γὰρ περισσεύματος καρδίας), the mouth speaks (λαλεῖ τὸ στόμα αὐτοῦ).  The heart was considered the moral center of a person.  Thus, we often say a person has a good heart.  Just like a tree, if the heart is good or evil, it will show up in either good or evil deeds and words.  This is similar to Matthew, chapter 12:35, thus indicating a possible Q source.  Matthew had Jesus speak about the same theme that only good can come from good people and only bad can come from bad people.  This is a common-sense statement that talks about the good and the evil people.  The good or kind person brought good things out of his good treasure or storehouse.  The evil or wicked person brought evil things out of his evil treasure or storehouse.  There never was any ambiguity.  Your treasure, your storehouse, your heart, or your morality would be revealed in your words or deeds.  What do you reveal in your activities?
