“The angel Gabriel

Went

To a virgin

Engaged to a man,

Whose name was Joseph,

Of the house of David.

The virgin’s name

Was Mary.”

πρὸς παρθένον ἐμνηστευμένην ἀνδρὶ ᾧ ὄνομα Ἰωσὴφ, ἐξ οἴκου Δαυείδ, καὶ τὸ ὄνομα τῆς παρθένου Μαριάμ.

Luke has the angel Gabriel appear to Mary, as opposed to Matthew, chapter 1:20, who had an unnamed angel appear to Joseph in a dream.  This angel Gabriel went to a virgin (πρὸς παρθένον), who was engaged (ἐμνηστευμένην) to a man named Joseph (ἀνδρὶ ᾧ ὄνομα Ἰωσὴφ) from the house of David (ἐξ οἴκου Δαυείδ).  The name of this virgin was Mary (καὶ τὸ ὄνομα τῆς παρθένου Μαριάμ).  Thus, both stories from these 2 gospels concur that Mary and Joseph were the parents of Jesus.  Matthew said that Joseph had resolved to get rid of Mary, instead of taking her as his wife until the angel of the Lord appeared to him.  This unnamed angel reassured Joseph that he should not be afraid to take Mary as his wife.  Thus, God, via his angel, was trying to show Joseph that everything would be alright.  Here the emphasis is on Mary, a common name in first century Judaism based on the name of Mariam, the sister of Moses.  Mary was a virgin (παρθένου), someone who did not have sexual relations with the opposite sex, which would have been normal at this time for young girls before they were married.  However, she was engaged or betrothed to Joseph, who had Davidic ancestry.  In other words, the wedding contact had not been signed.  Thus, they were still involved with prenuptial arrangements.
