'Descendant' in the Bible

It was a memorial for the Israelites, that no outsider who is not a descendant of Aaron should approach to burn incense before the Lord, that he might not become like Korah and his company -- just as the Lord had spoken by the authority of Moses.

Pallu's descendant was Eliab.

Then the heads of the family groups of the Gileadites, the descendant of Machir, the descendant of Manasseh, who were from the Josephite families, approached and spoke before Moses and the leaders who were the heads of the Israelite families.
