To be an ambassador in the ancient world (Greek, Roman, or Jewish), as in modern times, involved three things: (1) a commissioning for a special assignment; (2) representing the sender; and (3) exercising the authority of the sender…the envoy represented the messenger and acted on his behalf and in his place, thus embodying his authority. To disregard or insult the envoy was to disregard or insult the sender – M.J. Harris
