luke 2 verse 5 in the king james version i grew up with:

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

luke 1 verses 26 and 27

And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth,

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

now i always took that espoused in context to mean betrothed, not married. although i was never 100% up on marriage customs of the time. they had a formal relationship, were planning on being married, she claims she was a virgin and she was very pregnant. that’s what i got.
