שמואל ב, פרק כ׳, פסוק כ״ה

A kingdom requires both earthly administration and spiritual guidance to function properly. During this stage of King David's reign, the leadership structure was carefully divided between civil officials handling affairs of state and religious figures guiding the spiritual life of the nation.

One key civil role was that of the chief scribe. This official was responsible for managing the kingdom's official records and financial accounts [רלב״ג]. Other perspectives view this position as something closer to a foreign minister, tasked with handling diplomatic relations and corresponding with neighboring nations in foreign languages [ביאור שטיינזלץ].

Alongside the civil government stood the religious leadership, headed jointly by Zadok and Abiathar. These two men served side by side as High Priests [מצודת דוד, רד״ק]. This unusual arrangement of having two individuals share the highest religious office was only possible because the permanent Temple had not yet been built. Without a centralized Temple service, there was no practical need to appoint a single priest to lead the entire system [ביאור שטיינזלץ].

Despite their shared title, authority was not divided equally between them. The primary approach among commentators is that Zadok held the main role and was the designated High Priest, while Abiathar acted as his deputy [מצודת דוד, רלב״ג]. This hierarchy was the result of a significant historical shift. Originally, Abiathar had served as the sole High Priest. However, during the chaotic period of Absalom's rebellion, he lost his ability to receive answers from God through the Urim and Thummim. As a result, his standing diminished, and he was forced to share his rank with Zadok [מלבי״ם]. Although Abiathar was demoted and pushed to the side, he was not entirely dismissed during David's lifetime. He maintained his role as a chief priest until King Solomon ascended the throne and permanently removed him from the position [רד״ק].
