Archelaus - (Easton's Bible Dictionary)
Ruler of the people, son of Herod the Great, by Malthace, a Samaritan woman. He was educated along with his brother Antipas at Rome. He inherited from his father a third part of his kingdom viz., Idumea, Judea, and Samaria, and hence is called "king" (Matt. 2:22). It was for fear of him that Joseph and Mary turned aside on their way back from Egypt. Till a few days before his death Herod had named Antipas as his successor, but in his last moments he named Archelaus.
