[273] Abdon also, the son of Hilel, of the tribe of Ephraim, and born at the city Pyrathon, was ordained their supreme governor after Helon. He is only recorded to have been happy in his children; for the public affairs were then so peaceable, and in such security, that neither did he perform any glorious action. He had forty sons, and by them left thirty grandchildren; and he marched in state with these seventy, who were all very skillful in riding horses; and he left them all alive after him. He died an old man, and obtained a magnificent burial in Pyrathon.
