'Claim' in the Bible

Your claim to have a strategy and military strength is just empty talk. In whom are you trusting that you would dare to rebel against me?

But in the seventh month Ishmael the son of Nethaniah, the son of Elishama, of the royal family [who had a claim to be governor], came with ten men and struck and killed Gedaliah and the Jews and the Chaldeans who were with him at Mizpah.
