Letter to Caroline Sturgis
p303“At least for four weeks past it has seemed as if there were no great stock of oil to feed my wick. Perhaps the cruise may be filled again by some prophet before thou comest.”

Inferred Fuller alludes to 1 Kings 17:12–16 (KJV), the story of the prophet Elijah and the widow of Zarephath, whose "cruse of oil" was continually replenished by God despite drought and famine.
