Matthew 12:33-35

Young's Literal Translation

³³ `Either make the tree good, and its fruit good, or make the tree bad, and its fruit bad, for from the fruit is the tree known.

³⁴ `Brood of vipers! how are ye able to speak good things -- being evil? for out of the abundance of the heart doth the mouth speak.

³⁵ The good man out of the good treasure of the heart doth put forth the good things, and the evil man out of the evil treasure doth put forth evil things.
