'Son in law' in the Bible

And David said unto Saul - Who am, I, or who are my kinsfolk, the family of my father, in Israel, - that I should become son-in-law, to the king?

And Saul said to himself - I will give her unto him, that she may prove to him a snare, and that, the hand of the Philistines, may be upon him. So then Saul said unto David, A second time, mayest thou become my son-in-law to-day.

And Saul commanded his servants - Speak ye unto David quietly saying, Lo! the king delighteth in thee, and, all his servants, love thee, - now, therefore, become thou son-in-law to the king.

And the servants of Saul spake, in the ears of David, these words. And David said - Seemeth it a light thing, in your eyes, to become son-in-law to the king, seeing that, I, am a poor man and lightly esteemed?

So, when his servants told David these words, the thing was right in the eyes of David, to become son-in-law unto the king, - and the days had not expired.

Wherefore David arose, and went - he and his men, and smote among the Philistines two hundred men, and David brought in their foreskins, and gave them in full tale unto the king, that he might become son-in-law unto the king, and Saul gave him Michal his daughter, to wife.

Then Ahimelech answered the king, and said, - But who, among all thy servants, like David, is, faithful, being son-in-law to the king, and, cometh near to have audience with thee, and is, honoured in thy household?
