'Son in law' in the Bible

For there were many in Judah sworn unto him, because he was the son-in-law of Shecaniah the son of Arah; and his son Jehohanan had married the daughter of Meshullam the son of Berechiah.

And one of the sons of Jehoiada, the son of Eliashib the high priest, was son-in-law to Sanballat the Horonite: therefore I chased him from me.
