Proverbs 19:27

If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder, And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them; Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul. Ye shall walk after the LORD your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him.

And the LORD said unto him, Wherewith? And he said, I will go forth, and I will be a lying spirit in the mouth of all his prophets. And he said, Thou shalt persuade him, and prevail also: go forth, and do so. Now therefore, behold, the LORD hath put a lying spirit in the mouth of all these thy prophets, and the LORD hath spoken evil concerning thee. But Zedekiah the son of Chenaanah went near, and smote Micaiah on the cheek, and said, Which way went the Spirit of the LORD from me to speak unto thee? And Micaiah said, Behold, thou shalt see in that day, when thou shalt go into an inner chamber to hide thyself. And the king of Israel said, Take Micaiah, and carry him back unto Amon the governor of the city, and to Joash the king's son; And say, Thus saith the king, Put this fellow in the prison, and feed him with bread of affliction and with water of affliction, until I come in peace. And Micaiah said, If thou return at all in peace, the LORD hath not spoken by me. And he said, Hearken, O people, every one of you.

Go from the presence of a foolish man, when thou perceivest not in him the lips of knowledge.

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.

And he said unto them, Take heed what ye hear: with what measure ye mete, it shall be measured to you: and unto you that hear shall more be given.

He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me. Howbeit in vain do they worship me, teaching for doctrines the commandments of men. For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do. And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition. For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death: But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free. And ye suffer him no more to do ought for his father or his mother; Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye. And when he had called all the people unto him, he said unto them, Hearken unto me every one of you, and understand:
