And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS.

People's New Testament

1:30-33 Fear not. In the angel's message we have, (1) An assurance, Fear not. (2) A promise, Thou shalt bring forth a son (Lu 1:31). (3) A command, Thou shalt call his name JESUS (Lu 1:31). (4) A prophecy, He shall be great, the Son of the Highest, sit on David's throne, reign forever (Lu 1:32).

Jamieson-Fausset-Brown Bible Commentary

31. The angel purposely conforms his language to Isaiah's famous prophecy (Isa 7:14) [Calvin].

Matthew Henry's Concise Commentary

1:26-38 We have here an account of the mother of our Lord; though we are not to pray to her, yet we ought to praise God for her. Christ must be born miraculously. The angel's address means only, Hail, thou that art the especially chosen and favoured of the Most High, to attain the honour Jewish mothers have so long desired. This wondrous salutation and appearance troubled Mary. The angel then assured her that she had found favour with God, and would become the mother of a son whose name she should call Jesus, the Son of the Highest, one in a nature and perfection with the Lord God. JESUS! the name that refreshes the fainting spirits of humbled sinners; sweet to speak and sweet to hear, Jesus, a Saviour! We know not his riches and our own poverty, therefore we run not to him; we perceive not that we are lost and perishing, therefore a Saviour is a word of little relish. Were we convinced of the huge mass of guilt that lies upon us, and the wrath that hangs over us for it, ready to fall upon us, it would be our continual thought, Is the Saviour mine? And that we might find him so, we should trample on all that hinders our way to him. Mary's reply to the angel was the language of faith and humble admiration, and she asked no sign for the confirming her faith. Without controversy, great was the mystery of godliness, God manifest in the flesh, 1Ti 3:16. Christ's human nature must be produced so, as it was fit that should be which was to be taken into union with the Divine nature. And we must, as Mary here, guide our desires by the word of God. In all conflicts, let us remember that with God nothing is impossible; and as we read and hear his promises, let us turn them into prayers, Behold the willing servant of the Lord; let it be unto me according to thy word.
