Abiathar
Abiathar was a priest at the time of David and Solomon (ca. 1010-926 BC). Information about him can be found in the biblical books of the Old Testament ( 2 Sam 22,22 timely information to 1 Kings 4:4; theologically reflected information: 1 Chr 15.11 to 27.34 ). He was involved in the struggle for power in Israel and Judah. Solomon is said to have finally rejected him.
In the New Testament it only called Mark, in order to make a deadline.
