1: “betrothed to him”
This statement is wrong and right at the same time. They were now a married couple by law and by ritual, yet they were not married in the physical/sexual sense of the word. Luke was inspired to write it this way in order to highlight the fact that they had not yet consummated the marriage, and therefore the child to be born could not be Joseph’s son. Matthew 1:25 makes it clear that Joseph took Marry home as his wife after he heard from the angel but he did not have sexual relations with her until after the child was born.
