Mbh 5.34.2c

As fuel that is wet burneth with that which is dry, so a sinless man is punished equally with the sinful in consequence of constant association with the latter. Therefore, friendship with the sinful should be avoided. He that, from ignorance, faileth to control his five greedy foes, having five distinct objects, is overwhelmed by calamities. Guilelessness and simplicity, purity and contentment, sweetness of speech and self-restraint, truth and steadiness,--these are never the attributes of the wicked. Self-knowledge and steadiness, patience and devotion to virtue, competence to keep counsels and charity,--these, O Bharata, never exist in inferior men. Fools seek to injure the wise by false reproaches and evil speeches. The consequence is, that by this they take upon themselves the sins of the wise, while the latter, freed from their sins, are forgiven. In malice lieth the strength of the wicked; in criminal code, the strength of kings, in attentions of the weak and of women; and in forgiveness that of the virtuous. To control speech, O king, is said to be most difficult. It is not easy to hold a long conversation uttering words full of meaning and delightful to the hearers. Well-spoken speech is productive of many beneficial results; and ill-spoken speech, O king, is the cause of evils. A forest pierced by arrows, or cut down by hatchets may again grow, but one’s heart wounded and censured by ill-spoken words never recovereth. Weapons, such as arrows, bullets, and bearded darts, can be easily extracted from the body, but a wordy dagger plunged deep into the heart is incapable of being taken out. Wordy arrows are shot from the mouth; smitten by them one grieveth day and night. A learned man should not discharge such arrows, for do they not touch the very vitals of others. He, to whom the gods ordain defeat, hath his senses taken away, and it is for this that he stoopeth to ignoble deeds.
