“And if you pay attention to the one who wears the fine clothing and say, ‘You sit here in a good place,’ while you say to the poor man, ‘You stand over there,’ or, ‘Sit down at my feet,’ have you not then made distinctions among yourselves and become judges with evil thoughts?”

Do Not Speak Empty Words

“If a brother or sister is poorly clothed and lacking in daily food, and one of you says to them, ‘Go in peace, be warmed and filled,’ without giving them the things needed for the body, what good is that? So also faith by itself, if it does not have works, is dead.”
James 2:15-17 

Do Tame Your Words for God and Good

“For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body. If we put bits into the mouths of horses so that they obey us, we guide their whole bodies as well. Look at the ships also: though they are so large and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs. So also the tongue is a small member, yet it boasts of great things.
     How great a forest is set ablaze by such a small fire! And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life, and set on fire by hell. For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by mankind, but no human being can tame the tongue. It is a restless evil, full of deadly poison. With it we bless our Lord and Father, and with it we curse people who are made in the likeness of God. From the same mouth come blessing and cursing. My brothers, these things ought not to be so. Does a spring pour forth from the same opening both fresh and salt water? Can a fig tree, my brothers, bear olives, or a grapevine produce figs? Neither can a salt pond yield fresh water.”
James 3:2-12 

Do Not Use Words Pridefully to Build Yourself Up

“But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth.”
James 3:14

Do Not Use Words Selfishly

“What causes quarrels and what causes fights among you? Is it not this, that your passions are at war within you? You desire and do not have, so you murder. You covet and cannot obtain, so you fight and quarrel. You do not have, because you do not ask. You ask and do not receive, because you ask wrongly, to spend it on your passions.”
James 4:1-3

Do Not Use Words to Tear Others Down

“Do not speak evil against one another, brothers. The one who speaks against a brother or judges his brother, speaks evil against the law and judges the law. But if you judge the law, you are not a doer of the law but a judge.”
James 4:11

Do Not Use Words Presumptuously but Trustingly

“Come now, you who say, “Today or tomorrow we will go into such and such a town and spend a year there and trade and make a profit”— yet you do not know what tomorrow will bring. What is your life? For you are a mist that appears for a little time and then vanishes. Instead you ought to say, “If the Lord wills, we will live and do this or that.” As it is, you boast in your arrogance. All such boasting is evil.”
James 4:13-16

Do Not Use Words to Grumble

“Do not grumble against one another, brothers, so that you may not be judged; behold, the Judge is standing at the door.”
