'Son in law' in the Bible

for many in Judah are sworn to him, for he is son-in-law to Shechaniah son of Arah, and Jehohanan his son hath taken the daughter of Meshullam son of Berechiah;

And one of the sons of Joiada son of Eliashib the high priest, is son-in-law to Sanballat the Horonite, and I cause him to flee from off me.
