Sanballat is mentioned 10 times in scripture, across 1 book of the Old Testament. First named in scripture around 446 BC.
Held some place of authority in Samaria when Nehemiah went up to Jerusalem to rebuild its ruined walls. He vainly attempted to hinder this work (Neh. 2:10, 19; 4:1-12; 6). His daughter became the wife of one of the sons of Joiada, a son of the high priest, much to the grief of Nehemiah (13:28).
