Ephesians 4:21-25

if so be that ye heard him, and were taught in him, even as truth is in Jesus: that ye put away, as concerning your former manner of life, the old man, that waxeth corrupt after the lusts of deceit; and that ye be renewed in the spirit of your mind, and put on the new man, that after God hath been created in righteousness and holiness of truth. Wherefore, putting away falsehood, speak ye truth each one with his neighbor: for we are members one of another.
