A good man out of the good treasure of the heart brings forth good things: and an evil man out of the evil treasure brings forth evil things.
All Commentaries on Matthew 12:35 Go To Matthew 12
Rabanus Maurus
AD 856
Or the words, “Generation of vipers,” may be taken as signifying children, or imitators of the Devil, because they had wilfully spoken against good works, which is of the Devil, and thence follows, “Out of the abundance of the heartthe mouth speaketh.” That man speaks out of the abundance of the heart who isnot ignorant with what intention his words are uttered; and to declare his meaning more openly He adds, “A good man, out of the good treasure of his heartbringeth forth good things.” The treasure of the heart is the intention of the thoughts, by which the Judge judges that work which is produced, so that sometimes though the outward work that is shown seem great, yet because of the carelessness of a cold heart, they receive a little reward from the Lord.
