'Priests' in the Bible

These are the names of Aaron’s sons, the anointed priests, who were ordained to serve as priests.

But Nadab and Abihu died in the Lord’s presence when they presented unauthorized fire before the Lord in the Wilderness of Sinai, and they had no sons. So Eleazar and Ithamar served as priests under the direction of Aaron their father.

The sons of Aaron, the priests, are to sound the trumpets. Your use of these is a permanent statute throughout your generations.
