Titus 1:10

"From which some having swerved have turned aside unto vain jangling; having...: or, not aiming at"

"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world."

"And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:"

"That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;"

"And when Peter was come up to Jerusalem, they that were of the circumcision contended with him,"

"But evil men and seducers shall wax worse and worse, deceiving, and being deceived."

"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."
