'Descendant' in the Bible

But they shall serve the Lord their God and [the descendant of] David their King, whom I will raise up for them.

For thus says the Lord, ‘David shall never lack a man (descendant) to sit on the throne of the house of Israel;

and the Levitical priests shall never lack a man (descendant) to offer burnt offerings before Me and to burn grain offerings and to prepare sacrifices all day long.’”

therefore thus says the Lord of hosts, the God of Israel, “Jonadab the son of Rechab shall never fail to have a man (descendant) to stand before Me always.”’”
