'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 taken the daughter of Meshullam the son of Berechiah to wife.

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