John 2:6
Nearby stood six stone water jars, the kind used by the Jews for ceremonial washing, each holding from twenty to thirty gallons — the detailed specification of the jars' material (stone), number (six), and purpose (Jewish purification) is theologically loaded. Stone jars resist impurity better than clay; their ceremonial function connects to Jewish Law. The quantity (120-180 gallons) vastly exceeds wedding necessity, foreshadowing supernatural abundance.
