'Son in law' in the Bible

For there were many in Judah sworn to him; for he was a son-in-law of Shechaniah the son of Arah; and his son Johanan had taken the daughter of Meshullam the son of Berechiah.

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