'Descendants' in the Bible

But My servant Caleb, because he has a different spirit and has followed Me fully, I will bring into the land into which he entered, and his descendants shall take possession of it.

as a reminder to the sons of Israel so that no layman—that is, one who is not of the descendants of Aaron should approach to offer incense before the Lord; so that he will not become like Korah and as his company—just as the Lord had said to him through Moses.

“Who can count the dust (the descendants) of JacobAnd the number of even the fourth part of Israel?Let me die the death of the righteous [those who are upright and in right standing with God],And let my end be like his!”

“But ships shall come from the coast of Kittim,And shall afflict Asshur (Assyria) and Eber;So they (the victors) also will come to destruction.”

And it shall be for him and his descendants after him, a covenant of an everlasting priesthood, because he was jealous (impassioned) for [the unique honor and respect owed to] his God and made atonement for the sons of Israel.’”
