³⁴ O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

⁴⁵ A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.

¹⁸ But those things which proceed out of the mouth come forth from the heart; and they defile the man.

²⁹ Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.

¹³ As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but mine hand shall not be upon thee.

⁵ Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!

⁶ And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.

⁷ For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind:

⁸ But the tongue can no man tame; it is an unruly evil, full of deadly poison.

¹⁰ In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.

³⁵ A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.

⁴⁴ Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

⁶ For the vile person will speak villany, and his heart will work iniquity, to practise hypocrisy, and to utter error against the Lord, to make empty the soul of the hungry, and he will cause the drink of the thirsty to fail.
