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.
in word: The first area in which Timothy is to be an example is in "speech." Paul probably is referring to Timothy’s personal private conversation since his public orations are discussed in verse 13. His speech is to be absolutely truthful (Colossians 4:6; Matthew 5:37). The various sins of the tongue listed in the scriptures must not stain the lips of God’s preacher.
