Romans 3:9-19
9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
10 As it is written, There is none righteous, no, not one:
11 There is none that understandeth, there is none that seeketh after God.
12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
13 Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
14 Whose mouth is full of cursing and bitterness:
15 Their feet are swift to shed blood:
16 Destruction and misery are in their ways:
17 And the way of peace have they not known:
18 There is no fear of God before their eyes.
19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
James 3:2-13
2 For in many things we offend all. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.
3 Behold, we put bits in the horses' mouths, that they may obey us; and we turn about their whole body.
4 Behold also the ships, which though they be so great, and are driven of fierce winds, yet are they turned about with a very small helm, whithersoever the governor listeth.
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.
9 Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.
10 Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.
11 Doth a fountain send forth at the same place sweet water and bitter?
12 Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
13 Who is a wise man and endued with knowledge among you? let him show out of a good conversation his works with meekness of wisdom.
