'Son in law' in the Bible

For many in Judah were bound by oath to him, since he was a son-in-law of Shecaniah son of Arah, and his son Jehohanan had married the daughter of Meshullam son of Berechiah.

Even one of the sons of Jehoiada, son of Eliashib the high priest, had become a son-in-law to Sanballat the Horonite. So I drove him away from me.
