'Sons in law' in the Bible

Then the two visitors said to Lot, "Who else do you have here? Do you have any sons-in-law, sons, daughters, or other relatives in the city? Get them out of this place

Then Lot went out and spoke to his sons-in-law who were going to marry his daughters. He said, "Quick, get out of this place because the Lord is about to destroy the city!" But his sons-in-law thought he was ridiculing them.
