{Chief publican} (architel(936e)(8873)). The word occurs nowhere
else apparently but the meaning is clear from the other words
with archi- like archiereus (chief priest) archipoim(886e)
(chief shepherd). Jericho was an important trading point for
balsam and other things and so Zacchaeus was the head of the tax
collections in this region, a sort of commissioner of taxes who
probably had other publicans serving under him.
