Proverbs 13:17

As the cold of snow in the time of harvest, so is a faithful messenger to them that send him: for he refresheth the soul of his masters.

So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me. When I say unto the wicked, O wicked man, thou shalt surely die; if thou dost not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood will I require at thine hand.

Moreover it is required in stewards, that a man be found faithful.

Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God.

When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand.

And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry;

For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.

And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.

And I have seen folly in the prophets of Samaria; they prophesied in Baal, and caused my people Israel to err. I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness: they are all of them unto me as Sodom, and the inhabitants thereof as Gomorrah. Therefore thus saith the Lord of hosts concerning the prophets; Behold, I will feed them with wormwood, and make them drink the water of gall: for from the prophets of Jerusalem is profaneness gone forth into all the land. Thus saith the Lord of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the Lord.

The prophet that hath a dream, let him tell a dream; and he that hath my word, let him speak my word faithfully. What is the chaff to the wheat? saith the Lord.

As vinegar to the teeth, and as smoke to the eyes, so is the sluggard to them that send him.

The north wind driveth away rain: so doth an angry countenance a backbiting tongue.

He that sendeth a message by the hand of a fool cutteth off the feet, and drinketh damage.
