"Beware of false prophets, who, indeed, come to you in sheep's clothing, but within are ravening wolves.
"Behold, I send you forth as sheep in the midst of wolves; become ye, therefore, as wise as the serpents and as innocent as doves.
Go your ways; behold, I am sending you forth as lambs in the midst of wolves.
The hireling, who also is not a shepherd, whose own the sheep are not, beholds the wolf coming, and leaves the sheep, and flees (and the wolf seizes them, and scatters them);
2 Peter 2:1
But there arose false prophets also among the people, as among you also there will be false teachers, who, indeed, will stealthily bring in destructive heresies, denying even the Master Who bought them, bringing upon themselves swift destruction:
but to abide in flesh is more needful for you.
