'Son in law' in the Bible

For in Judah there were a number of people who had made an agreement by oath with him, because he was the son-in-law of Shecaniah, the son of Arah; and his son Jehohanan had taken as his wife the daughter of Meshullam, the son of Berechiah.

And one of the sons of Joiada, the son of Eliashib, the chief priest, was son-in-law to Sanballat the Horonite: so I sent him away from me.
