jad’-u-a, ja-du’-a (yaddua`, "known"):

(1) One of the "chiefs of the people" who with Nehemiah sealed the covenant, thus signifying their voluntary acceptance of the law and their solemn promise to submit to its yoke (Ne 10:21 (Hebrew 22)).

(2) Son of Jonathan or Johanan, and great-grandson of Eliashib, the high priest in Nehemiah’s time (Ne 12:11,22). He is the last of the high priests mentioned in the Old Testament, and held office during the reign of Darius the Persian, i.e. Darius III Codomannus, the last king of Persia (336-332 BC), who was overthrown by nodetitle. It is doubtless to him that Josephus refers in his romantic account of Alexander’s entrance into Jerusalem (Ant., XI, viii, 4 f; vii, 2; viii, 7).
