Aaron’s third son, Eleazar, led the Levites as an administrator. He was like an executive secretary, while his father did other tasks. He had "oversight of the entire tabernacle" (4:16–20). Eleazar had a key role during Israel’s time in the wilderness. He later became the high priest after his father (see 16:37–39; 19:3–6; 20:25–28; 26:1–3).
