'Son in law' in the Bible

And the Philistines say, 'Who hath done this?' And they say, 'Samson, son-in-law of the Timnite, because he hath taken away his wife, and giveth her to his companion;' and the Philistines go up, and burn her and her father with fire.

And it cometh to pass, on the fourth day, that they rise early in the morning, and he riseth to go, and the father of the young woman saith unto his son-in-law, 'Support thy heart with a morsel of bread, and afterward ye go on.'
