The Hebrew proper name Immer refers to a Levitical priest in the time of David who became the head of one of the 24 divisions of priests established by David (1 Chronicles 24:14). Priests bearing this name also appear after the return from Babylon. The name may derive from amar (to speak, declare) or relate to a word for 'lamb.'
The organization of the priesthood into 24 divisions by David ensured systematic, orderly worship — a foreshadowing of the new covenant's priesthood of all believers. The priestly families like Immer who returned from Babylon were part of God's promise to restore worship and the community of faith. Even the organizational details of Israel's worship reveal God's care for order, reverence, and access in His presence.
