SEV Biblia, Chapter 12:34
Generacin de víboras, ¿cmo podis hablar bien, siendo malos? Porque de la abundancia del corazn habla la boca.
Clarke's Bible Commentary - Matthew 12:34
Verse 34. O generation of vipers] These are apparently severe words; but they were extremely proper in reference to that execrable people to whom they were addressed: the whole verse is an inference from what was spoken before. Out of the abundance (perisseumatov, the overflowings) of the heart] Wicked words and sinful actions may be considered as the overflowings of a heart that is more than full of the spirit of wickedness; and holy words and righteous deeds may be considered as the overflowings of a heart that is filled with the Holy Spirit, and running over with love to God and man.
John Gill's Bible Commentary
Ver. 34. O generation of vipers , etc.] Though they boasted of their being the seed of Abraham, yet their immediate ancestors were no other than vipers, deceitful, hurtful, poisonous creatures; and they were exactly like them: for though they made a fair show in the flesh, and outwardly appeared righteous, yet were inwardly full of the poison of wickedness, envy and malice; and which their pestilential breath, their blasphemy against the Spirit, fully discovered; and gave just cause and reason for so severe a reproof, and such resentment, as here made by Christ. How can ye, being evil, speak good things? This is not to be expected, nor is it commonly and constantly done; an evil man may sometimes speak good things, or which seem to be so; but these are not his common talk; as he is, so, for the most part, is his language; his speech betrays him: and since these men were by nature evil, were destitute of the Spirit and grace of God, had no good thing in them, how should any good thing come out of them? And since they were so full of wickedness, spite and malice, it is no wonder that they belched out such blasphemous expressions concerning the miracles of Christ; for out of the abundance of the heart the mouth speaketh : a phrase much like this is used by the Septuagint, in ( Ecclesiastes 2:15). I spoke abundance, or much in my heart; dioto o afrwn ek perisseumatov lalei , for the fool out of his abundance speaketh: as there is abundance of folly in him, there is much delivered out by him; and where there is abundance of wickedness in the heart, if the grace of God is wanting to restrain it, much of it will come out by the lips; as is a mans heart, ordinarily is his language.
Matthew Henry Commentary
Verses 33-37 - Men's language discovers what country they are of, likewise what manne of spirit they are of. The heart is the fountain, words are the streams. A troubled fountain, and a corrupt spring, must send fort muddy and unpleasant streams. Nothing but the salt of grace, cast int 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, dwellin and reigning in the heart, are an evil treasure, out of which the sinner brings forth bad words and actions, to dishonour God, and hur others. Let us keep constant watch over ourselves, that we may spea words agreeable to the Christian character.

Robertson's NT Word Studies
12:34 {Ye offspring of vipers} (gennemata ecidnwn). These same terrible words the Baptist had used to the Pharisees and Sadducees who came to his baptism (#Mt 3:7). But these Pharisees had deliberately made their choice and had taken Satan's side. The charge against Jesus of being in league with Satan reveals the evil heart within. The heart "spurts out" (ekballei) good or evil according to the supply (treasure, thsaurou) within. Verse #33 is like #Mt 7:17-19. Jesus often repeated his crisp pungent sayings as every teacher does.
