but the one who restrains his words is wise.

but the righteous person escapes out of trouble.

Psalms 39:1

Psalm 39

For the music director, Jeduthun; a psalm of David.

39:1 I decided, “I will watch what I say

and make sure I do not sin with my tongue.

I will put a muzzle over my mouth

while in the presence of an evil man.”

Matthew 12:36-37

12:36 I tell you that on the day of judgment, people will give an account for every worthless word they speak. 12:37 For by your words you will be justified, and by your words you will be condemned.”

James 1:26

1:26 If someone thinks he is religious yet does not bridle his tongue, and so deceives his heart, his religion is futile.

James 3:2-12

3:2 For we all stumble in many ways. If someone does not stumble in what he says, he is a perfect individual, able to control the entire body as well. 3:3 And if we put bits into the mouths of horses to get them to obey us, then we guide their entire bodies. 3:4 Look at ships too: Though they are so large and driven by harsh winds, they are steered by a tiny rudder wherever the pilot’s inclination directs. 3:5 So too the tongue is a small part of the body, yet it has great pretensions. Think how small a flame sets a huge forest ablaze. 3:6 And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence – and is set on fire by hell.

3:7 For every kind of animal, bird, reptile, and sea creature is subdued and has been subdued by humankind. 3:8 But no human being can subdue the tongue; it is a restless evil, full of deadly poison. 3:9 With it we bless the Lord and Father, and with it we curse people made in God’s image. 3:10 From the same mouth come blessing and cursing. These things should not be so, my brothers and sisters. 3:11 A spring does not pour out fresh water and bitter water from the same opening, does it? 3:12 Can a fig tree produce olives, my brothers and sisters, or a vine produce figs? Neither can a salt water spring produce fresh water.
