'Son in law' in the Bible

And the Philistines said, Who has done this? And they answered, Samson, the son-in-law of the Timnite, because he had taken his wife and given her to his companion. And the Philistines came up and burned her and her father with fire.

And it happened on the fourth day when they arose early in the morning, he rose up to leave. And the girl's father said to his son-in-law, Comfort your heart with a piece of bread, and afterward go your way.
