1 Timothy 4:7; 1 Timothy 4:16; 1 Timothy 5:22

7 But refuse profane and old wives' fables, and exercise thyself rather unto godliness.
16 Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.
22 Lay hands suddenly on no man, neither be partaker of other men's sins: keep thyself pure.
