Matthew 1:20

An angel of the Lord appeared unto him in a dream (aggelo kuriou kat onar epanh autwi). This expression (aggelo kuriou) is without the article in the New Testament except when, as in Deuteronomy 1:24 , there is reference to the angel previously mentioned. Sometimes in the Old Testament Jehovah Himself is represented by this phrase. Surely Joseph needed God's help if ever man did. If Jesus was really God's Son, Joseph was entitled to know this supreme fact that he might be just to both Mary and her Child. It was in a dream, but the message was distinct and decisive for Joseph. He is called "Son of David" as had been shown by Matthew in Matthew 1:16 . Mary is called his "wife" (thn gunaika sou). He is told "not to become afraid" (ingressive first aorist passive subjunctive in prohibition, (mh pobhqh), "to take to his side" (paralabein, ingressive aorist active infinitive) her whom he had planned (enqumhqento, genitive absolute again, from en and qumo) to send away with a writ of divorce. He had pondered and had planned as best he knew, but now God had called a halt and he had to decide whether he was willing to shelter Mary by marrying her and, if necessary, take upon himself whatever stigma might attach to her. Joseph was told that the child was begotten of the Holy Spirit and thus that Mary was innocent of any sin. But who would believe it now if he told it of her? Mary knew the truth and had not told him because she could not expect him to believe it.
