'Espoused' in the Bible

Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.

To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin's name was Mary.

To be taxed with Mary his espoused wife, being great with child.

For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
