Abiathar

Definition:

Abiathar was a high priest for the nation of Israel during the time of King David.

When King Saul killed the priests, Abiathar escaped and went to David in the wilderness.
Abiathar and another high priest named Zadok served David faithfully throughout his reign.
After David's death, Abiathar helped Adonijah try to become king instead of Solomon.
Because of this, King Solomon removed Abiathar from the priesthood.
