“Beware of false prophets, who come to you in sheep’s clothing,”but are wolves.

  “Judge  not, that you be not judged. For with what  judgment you judge, you will be judged;  and with the measure you use, it will be measured back to you. And why do you look at the speck in your brother’s eye, but do not consider the plank in your own eye? Or how can you say to your brother, ‘Let me remove the speck from your eye’; and look, a plank is in your own eye? Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother’s eye. “Do not give what is holy to the dogs; nor cast your pearls before swine, lest they trample them under their feet, and turn and tear you in pieces. “Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For  everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened.    “Beware of false prophets,  who come to you in sheep’s clothing, but inwardly they are ravenous wolves. “Not everyone who says to Me,  ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who  does the will of My Father in heaven. Many will say to Me in that day, ‘Lord, Lord, have we  not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And  then I will declare to them, ‘I never knew you;  depart from Me, you who practice lawlessness!’ And so it was, when Jesus had ended these sayings, that the people were astonished at His teaching, for He taught them as one having authority, and not as the scribes. Matthew 7:1-12,15,21-23,28-29 - NKJV
