'Marriage' in the Bible

He must not make himself unclean [as] {a kinsman by marriage}, defiling himself.

He had thirty sons. He gave his thirty daughters away in marriage outside [his clan] and brought in from outside thirty young women for his sons. He judged Israel for seven years.

And the men of Israel said, "Did you see this man who has come up? For he [is] going up to defy Israel! It will be [that] the man who defeats him, the king will make him very rich with great wealth and will give him his daughter [in marriage] and will make his father's house free in Israel."

And [in] that you saw the iron was mixed with wet clay, [so] {they will mix in marriage} and they will not cling {to one another}, just as iron [does] not mix with clay.

But you ask, "{For what reason}?" Because Yahweh stands as a witness between you and the wife of your youth, against whom you have been unfaithful, even though she [is] your marriage partner and {your wife by covenant}.
