'Son in law' in the Bible

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

And it came to pass, on the fourth day, when they arose early in the morning, and gat up to go, that the father of the damsel said unto his son-in-law, - Stay thy heart with a morsel of bread, and, afterwards, ye shall go your way.
