'Son in law' in the Bible

Then the Philistines said, Who has done this? And they said, Samson, the son-in-law of the Timnite, because he took his wife and gave her to his friend. So the Philistines came up and had her and her father's house burned.

Now on the fourth day they got up early in the morning and he made ready to go away; but the girl's father said to his son-in-law, Take a little food to keep up your strength, and then go on your way.
