This noun denotes a treasury or treasure storehouse, particularly royal or governmental repositories of wealth. In Acts 8:27, the Ethiopian eunuch held authority over all the treasury of Candace, queen of the Ethiopians. The term encompasses both the physical location where treasure is kept and the treasure itself. Persian loanword origins suggest it entered Greek through contact with Eastern imperial administration. The translations (Spanish tesorería, German/French retaining the Greek or using similar cognates) emphasize the institutional treasury under the eunuch's supervision, befitting his high governmental position.
