דברי הימים א, פרק ט׳, פסוק כ״א

Tracing the lineage of those who served in holy roles, the historical record shifts its attention to the later generations of these dedicated workers [ביאור שטיינזלץ]. One such individual was Zechariah, the son of Meshelemiah, who was entrusted with the vital task of acting as a gatekeeper. He stood guard directly at the entrance gate of the Tabernacle [מצודת דוד]. To fulfill this duty, his specific watch post was located on the northern side of the Tabernacle [מלבי״ם].
