TETRARCH
TETRARCH strictly the ruler over the fourth part of a province; but the
word denotes a ruler of a province generally (Matthew 14=>1; Luke 3=>1, 19;
9=>7; Acts 13=>1). Herod and Phasael, the sons of Antipater, were the first
tetrarchs in Palestine. Herod the tetrarch had the title of king (Matthew
14=>9).
