The visit lasted about three months, after which time Mary returned to Nazareth. The real embarrassment of her position she had now to meet. At the home of her cousin she had been understood; her condition had served to confirm the testimony of Zacharias and Elisabeth; but how would her word be received at her own home? And especially, how would she be regarded by her espoused husband?[206] Betrothal, or espousal, in that time was in some respects as binding as the marriage vow, and could only be set aside by a ceremonial separation akin to divorce; yet an espousal was but an engagement to marry, not a marriage. When Joseph greeted his promised bride after her three months' absence, he was greatly distressed over the indications of her prospective maternity. Now the Jewish law provided for the annulment of a betrothal in either of two ways--by public trial and judgment, or by private agreement attested by a written document signed in the presence of witnesses. Joseph was a just man, a strict observer of the law, yet no harsh extremist; moreover he loved Mary and would save her all unnecessary humiliation, whatever might be his own sorrow and suffering. For Mary's sake he dreaded the thought of publicity; and therefore determined to have the espousal annulled with such privacy the law allowed. He was troubled and thought much of his duty in the matter, when, "behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins."[207] Great was Joseph's relief of mind; and great his joy in the realization that the long predicted coming of the Messiah was at hand; the words of the prophets would be fulfilled; a virgin, and she the one in the world most dear to him, had conceived, and in due time would bring forth that blessed Son, Emmanuel, which name by interpretation means "God with us."[208] The angel's salutation was significant; "Joseph, thou son of David," was the form of address; and the use of that royal title must have meant to Joseph that, though he was of kingly lineage, marriage with Mary would cast no shadow upon his family status. Joseph waited not; to insure Mary all possible protection and establish his full legal right as her lawful guardian he hastened the solemnization of the marriage, and "did as the angel of the Lord had bidden him, and took unto him his wife: and knew her not till she had brought forth her firstborn son: and he called his name JESUS."[209]
