21The wise in heart shall be called prudent: and the sweetness of the lips increaseth learning. 22Understanding is a wellspring of life unto him that hath it: but the instruction of fools is folly. 23The heart of the wise teacheth his mouth, and addeth learning to his lips. 24Pleasant words are as an honeycomb, sweet to the soul, and health to the bones.25There is a way that seemeth right unto a man, but the end thereof are the ways of death. 26He that laboureth laboureth for himself; for his mouth craveth it of him. 27An ungodly man diggeth up evil: and in his lips there is as a burning fire.
