Acts 24:16

Exercise myself [α σ κ ω]. Originally, to work raw material, to form : hence, to practice, exercise, discipline; and so, in ecclesiastical language, to mortify the body. Of the kindred adjective ajskhtikov, our word ascetic is a transcript.

Void of offense [α π ο σ κ ο π ο ν]. Lit., without stumbling; unshaken. The word is used thus in a passive sense here, as in Philippians 1:10. In 1 Corinthians 10:32, it occurs in the active sense of giving offense to others, causing them to stumble.
