For unto you is born this day,.... Day is here put for a natural day, consisting both of night and day; for it was night when Christ was born, and the angels brought the tidings of it to the shepherds.
The particular day, and it may be, month and year, in which Christ was born, cannot be certainly known; but this we may be sure of, it was in the fulness of time, and at the exact, season fixed upon between God and Christ in the council and covenant of peace; and that he was born, not unto, or for the good of angels; for the good angels stand in no need of his incarnation, sufferings, and death, having never fell; and as for the evil angels, a Saviour was never designed and provided for them; nor did Christ take on him their nature, nor suffer in their stead: wherefore the angel does not say, "unto us", but "unto you", unto you men; for he means not merely, and only the shepherds, or the Jews only, but the Gentiles also; all the children, all the spiritual seed of Abraham, all elect men; for their sakes, and on their account, and for their good, he assumed human nature; see Isa 9:6in the city of David; that is, Bethlehem, as in Lu 2:4 where the Messiah was to be born, as being, according to the flesh, of the seed of David, his son and offspring; as he is, according to his divine nature, his Lord and root.
