'Relatives' in the Bible

Adonijah sacrificed sheep, oxen, and fatted cattle by the Serpent Stone near En-rogel, inviting all of his relatives, the king's sons, and all of the men of Judah who worked for the king,

As soon as he had consolidated his reign, he executed the entire household of Baasha. He did not leave a single male alive, including any of Baasha's relatives or friends.
