33 "Either make the tree good, and its fruit good; or make the tree bad, and its fruit bad; for the tree is known by its fruit. 34 You brood of vipers! How can you speak good things, when you are evil? For out of the abundance of the heart the mouth speaks. 35 The good person brings good things out of a good treasure, and the evil person brings evil things out of an evil treasure. 36 I tell you, on the day of judgment you will have to give an account for every careless word you utter; 37 for by your words you will be justified, and by your words you will be condemned."
Matthew Henry's Commentary on Matthew 12:33-37
Commentary on Matthew 12:33-37
(Read Matthew 12:33-37)
Men's language discovers what country they are of, likewise what manner of spirit they are of. The heart is the fountain, words are the streams. A troubled fountain, and a corrupt spring, must send forth muddy and unpleasant streams. Nothing but the salt of grace, cast into the spring, will heal the waters, season the speech, and purify the corrupt communication. An evil man has an evil treasure in his heart, and out of it brings forth evil things. Lusts and corruptions, dwelling and reigning in the heart, are an evil treasure, out of which the sinner brings forth bad words and actions, to dishonour God, and hurt others. Let us keep constant watch over ourselves, that we may speak words agreeable to the Christian character.
