Do not use God’s name in vain.
"neither shalt thou profane the name of thy God: I am the LORD."
"Now therefore, what have I here, saith the LORD, that my people is taken away for nought? they that rule over them make them to howl, saith the LORD; and my name continually every day is blasphemed."
"For the land is full of adulterers; for because of swearing the land mourneth; the pleasant places of the wilderness are dried up, and their course is evil, and their force is not right. For both prophet and priest are profane; yea, in my house have I found their wickedness, saith the LORD."

"My brethren, be not many masters, knowing that we shall receive the greater condemnation. 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. Behold, we put bits in the horses' mouths, that they may obey us; and we turn about their whole body. 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. Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth! 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. 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: But the tongue can no man tame; it is an unruly evil, full of deadly poison. Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God. Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be. Doth a fountain send forth at the same place sweet water and bitter? Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh. Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom.

"And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy."
