 Potiphar
    dedicated to Ra; i.e., to the sun-god, the Egyptian to whom the
    Ishmaelites sold Joseph (Gen. 39:1). He was "captain of the
    guard", i.e., chief, probably, of the state police, who, while
    they formed part of the Egyptian army, were also largely
    employed in civil duties (37:36; marg., "chief of the
    executioners"). Joseph, though a foreigner, gradually gained his
    confidence, and became overseer over all his possessions.
    Believing the false accusation which his profligate wife brought
    against Joseph, Potiphar cast him into prison, where he remained
    for some years. (See JOSEPH.)
