n.

late 14c., also emb-ssador, from middle french amb-ssadeur, from old french emb-ssator, via provençal or old spanish from latin ambactus “a servant, v-ssal,” from celtic amb(i)actos “a messenger, servant,” from pie -ambhi- “about” (see ambi-) + -ag- “drive, lead” (see act (v.)). cf. emb-ssy. forms in am- and em- were used indiscriminately 17c.-18c.

in the old testament the hebrew word _tsir_, meaning “one who goes on an errand,” is rendered thus (josh. 9:4; prov. 13:17; isa. 18:2; jer. 49:14; obad. 1:1). this is also the rendering of _melits_, meaning “an interpreter,” in 2 chr. 32:31; and of _malak_, a “messenger,” in 2 chr. 35:21; isa. 30:4; 33:7; ezek. 17:15. this is the name used by the apostle as designating those who are appointed by g-d to declare his will (2 cor. 5:20; eph. 6:20). the hebrews on various occasions and for various purposes had recourse to the services of amb-ssadors, e.g., to contract alliances (josh. 9:4), to solicit favours (num. 20:14), to remonstrate when wrong was done (judg. 11:12), to condole with a young king on the death of his father (2 sam. 10:2), and to congratulate a king on his accession to the throne (1 kings 5:1). to do injury to an amb-ssador was to insult the king who sent him (2 sam. 10:5).
