Numbers 3:4

2-4. And these are the names of the sons of Aaron—All the sons of Aaron, four in number, were consecrated to minister in the priest's office. The two oldest enjoyed but a brief term of office (Le 10:1, 2; Nu 3:4; 26:61); but Eleazar and Ithamar, the other two, were dutiful, and performed the sacred service during the lifetime of their father, as his assistants, and under his superintendence.
