The Greek adjective asitos (ἄσιτος) means "without food, fasting, not having eaten" — from the alpha-privative a- and sitos (grain, food). It describes the condition of a person who has gone without eating, whether by choice, necessity, or exhaustion. The word appears once in the New Testament.
In Acts 27:33, at the climax of the ship's crisis, Paul urges the 276 people aboard to eat: "Today is the fourteenth day that you have waited and gone without food (asitoi) — you haven't eaten anything." Paul then takes bread, gives thanks to God in full view of everyone, and eats — a eucharistic-like scene that brings courage to all. Luke notes "they were all encouraged and ate some food themselves" (27:36). Paul's act of eating by faith — after fourteen days without food during a deadly storm — is a quiet miracle of spiritual leadership. Bodily sustenance was provided so they could complete God's purposes for their lives.
