1 Enoch 107:1
1 And I saw written on them that generation upon generation shall transgress, till a generation of righteousness arises, and transgression is destroyed and sin passes away from the earth, and all manner of good comes upon it. 2 And now, my son, go and make known to thy son Lamech that this son, which has been born, is in truth his son, and that (this) is no lie.' 3 And when Methuselah had heard the words of his father Enoch--for he had shown to him everything in secret--he returned and showed (them) to him and called the name of that son Noah; for he will comfort the earth after all the destruction.
Matthew 1:21
18 Now the birth of Jesus Christ happened this way. While his mother Mary was engaged to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit. 19 Because Joseph, her husband to be, was a righteous man, and because he did not want to disgrace her, he intended to divorce her privately. 20 When he had contemplated this, an angel of the Lord appeared to him in a dream and said, “Joseph, son of David, do not be afraid to take Mary as your wife because the child conceived in her is from the Holy Spirit. 21 She will give birth to a son and you will name him Jesus because he will save his people from their sins.” 22 This all happened so that what was spoken by the Lord through the prophet would be fulfilled: 23 “Look! The virgin will conceive and give birth to a son, and they will name him Emmanuel,” which means “God with us.” 24 When Joseph awoke from sleep he did what the angel of the Lord told him. He took his wife, 25 but did not have marital relations with her until she gave birth to a son, whom he named Jesus.
