'Son in law' in the Bible

Then the Philistines said, Who hath 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 burnt her and her father with fire.

And it came to pass on the fourth day, when they arose early in the morning, that he arose to depart: and the damsel's father said to his son-in-law, Comfort thy heart with a morsel of bread, and afterward depart.
