'Family' in the Bible

He walked in the way of the house of Ahab and did what was evil in the Lord’s sight like the house of Ahab, for he was a son-in-law to Ahab’s family.

In the seventh month, however, Ishmael son of Nethaniah, son of Elishama, of the royal family, came with 10 men and struck down Gedaliah, and he died. Also, they killed the Judeans and the Chaldeans who were with him at Mizpah.
