1. For which reason the Lord declared to the disciples: “Behold, I say unto you, Lift up your eyes, and look upon the districts (regiones), for they are white [already] to harvest. For the harvest-man receiveth wages, and gathereth fruit unto life eternal, that both he that soweth and he that reapeth may rejoice together. For in this is the saying true, that one soweth and another reapeth. For I have sent you forward to reap that whereon ye bestowed no labour; other men have laboured, and ye have entered into their labours.” Who, then, are they that have laboured, and have helped forward the dispensations of God? It is clear that they are the patriarchs and prophets, who even prefigured our faith, and disseminated through the earth the advent of the Son of God, who and what He should be: so that posterity, possessing the fear of God, might easily accept the advent of Christ, having been instructed by the prophets. And for this reason it was, that when Joseph became aware that Mary was with child, and was minded to put her away privily, the angel said to him in sleep: “Fear not to take to thee Mary thy wife; for that which is conceived in her is of the Holy Ghost. For she shall bring forth a son, and thou shalt call His name Jesus; for He shall save His people from their sins.” And exhorting him [to this], he added: “Now all this has been done, that it might be fulfilled which was spoken from the Lord by the prophet, saying, Behold, a virgin shall be with child, and shall bring forth a son, and His name shall be called Emmanuel;” thus influencing him by the words of the prophet, and warding off blame from Mary, pointing out that it was she who was the virgin mentioned by Isaiah beforehand, who should give birth to Emmanuel. Wherefore, when Joseph was convinced beyond all doubt, he both did take Mary, and joyfully yielded obedience in regard to all the rest of the education of Christ, undertaking a journey into Egypt and back again, and then a removal to Nazareth. [For this reason,] those who knew not the Scriptures nor the promise of God, nor the dispensation of Christ, at last called him the father of the child. For this reason, too, did the Lord Himself read at Capernaum the prophecies of Isaiah: “The Spirit of the Lord is upon Me, because He hath anointed Me; to preach the Gospel to the poor hath He sent Me, to heal the broken-hearted, to preach deliverance to the captives, and sight to the blind.” At the same time, showing that it was He Himself who had been foretold by Esaias the prophet, He said to them: “This day is this Scripture fulfilled in your ears.”
