For every nature, both of beasts and of fowls, both of creeping things and things of the sea, is subdued, and has been subdued, by the human nature,

and the tongue no one of men is able to subdue, it is an unruly evil, full of deadly poison,

Tiago 3:7,8

9 wherefore, also, God did highly exalt him, and gave to him a name that is above every name,

10 that in the name of Jesus every knee may bow -- of heavenlies, and earthlies, and what are under the earth --

11 and every tongue may confess that Jesus Christ is Lord, to the glory of God the Father.

Filipenses 2:9-11

If with the tongues of men and of messengers I speak, and have not love, I have become brass sounding, or a cymbal tinkling;

1 Coríntios 13:1

for we all make many stumbles; if any one in word does not stumble, this one is a perfect man, able to bridle also the whole body;

Tiago 3:2

'And I say to you, that every idle word that men may speak, they shall give for it a reckoning in a day of judgment;

for from your words you shall be declared righteous, and from your words you shall be declared unrighteous.'

Mateus 12:36,37

9 with it we do bless the God and Father, and with it we do curse the men made according to the similitude of God;

10 out of the same mouth does come forth blessing and cursing; it does not need, my brethren, these things so to happen;

11 does the fountain out of the same opening pour forth the sweet and the bitter?

12 is a fig-tree able, my brethren, olives to make? or a vine figs? so no fountain salt and sweet water is able to make.

Tiago 3:9-12

If any one does think to be religious among you, not bridling his tongue, but deceiving his heart, of this one vain is the religion;

Tiago 1:26

3 lo, the bits we put into the mouths of the horses for their obeying us, and their whole body we turn about;

4 lo, also the ships, being so great, and by fierce winds being driven, are led about by a very small helm, whithersoever the impulse of the helmsman does counsel,

5 so also the tongue is a little member, and does boast greatly; lo, a little fire how much wood it does kindle!

6 and the tongue is a fire, the world of the unrighteousness, so the tongue is set in our members, which is spotting our whole body, and is setting on fire the course of nature, and is set on fire by the gehenna.

Tiago 3:3-6
