'Marriage' in the Bible

He had thirty sons, and thirty daughters whom he gave in marriage outside the family, and he brought in thirty daughters from outside for his sons. And he judged Israel seven years.

Now the men of Israel had sworn in Mizpah, saying, “None of us shall give his daughter to Benjamin in marriage.”

What shall we do for wives for those who are left, since we have sworn by the Lord not to give them any of our daughters in marriage?”
