      n 1: a diplomat of the highest rank; accredited as representative
           from one country to another [syn: embassador]
      2: an informal representative; "an ambassador of good will"
 Ambassador
    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 God 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 ambassadors, 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 ambassador was to insult the king who sent
    him (2 Sam. 10:5).
