'Kingship' in the Bible

Pul, [Tiglath-pileser III] king of Assyria, came against the land [of Israel], and Menahem gave Pul a thousand talents of silver [as a bribe], so that he might help him to strengthen his control of the kingdom.

But it happened in the seventh month that Ishmael the son of Nethaniah the son of Elishama from the offspring of the kingship came, and ten men with him, and they struck down Gedaliah so that he died with the Judeans and with the Chaldeans who were with him at Mizpah.
