Cursing

Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain.

As he loved cursing, so let it come unto him: as he delighted not in blessing, so let it be far from him.

Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.

And he called the multitude, and said unto them, Hear, and understand:

Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.

But those things which proceed out of the mouth come forth from the heart; and they defile the man.

For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

These are the things which defile a man: but to eat with unwashen hands defileth not a man.

Bless them that curse you, and pray for them which despitefully use you.

Bless them which persecute you: bless, and curse not.

Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.

Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.

But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.

Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man.

If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain.

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.
