Take the sum of the sons of Caath from the midst of the Levites, by their houses and families.
Of the kindred of Caath come the families of the Amramites and Jesaarites and Hebronites and Ozielites. These are the families of the Caathites reckoned up by their names:
The sons of Caath: Amram, and Jesaar, Hebron and Oziel.
And the Lord spoke to Moses, and Aaron, saying:
From thirty years old and upward, to fifty years old; of all that go in to stand and to minister in the tabernacle of the covenant.
