Let no man despise your youth; but be an example to those who believe, in word, in your way of life, in love, in spirit, in faith, and in purity.
The words "in spirit" that appear in the King James Version do not appear in the vast majority of manuscripts. They do not appear in the Nestle text (The Zondervan Parallel New Testament in Greek and English 617) nor in most English versions since 1611. In all probability, these words are a gloss inserted later into the text.
