2 Timothy 2:15-18

Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. But shun profane and vain babblings: for they will increase unto more ungodliness. And their word will eat as doth a canker: of whom is Hymenæus and Philetus; who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.
