The name “Abiathar” is of Hebrew origin and is found in the Old Testament of the Bible. It means “father of abundance” or “my father is great.” In the biblical narrative, Abiathar is a significant figure:

1. **Priestly Role**: Abiathar was a high priest during the reign of King David. He played a crucial role in David’s ascension to the throne and was one of his loyal supporters.

2. **Son of Ahimelech**: He was the son of Ahimelech, the priest of Nob. Abiathar escaped the massacre ordered by King Saul, where many priests were killed, and he fled to David with the ephod, an important priestly garment (1 Samuel 22:20-23).

3. **Involvement in David’s Reign**: Throughout David’s reign, Abiathar continued to serve as a priest. He was involved in significant events and decisions and was a key member of David’s court.

4. **End of Service**: His service ended after he supported Adonijah instead of Solomon as David’s successor. Solomon, upon becoming king, removed Abiathar from his position, fulfilling a prophecy against the house of Eli (1 Kings 2:26-27).

Abiathar’s name, with its connotations of abundance and greatness, reflects his high status and the significant role he played during a pivotal period in Israel’s history.
