Isaiah 7:12-14 Douay-Rheims 1899 American Edition (DRA)
12 And Achaz said: I will not ask, and I will not tempt the Lord.
13 And he said: Hear ye therefore, O house of David: Is it a small thing for you to be grievous to men, that you are grievous to my God also?
14 Therefore the Lord himself shall give you a sign. Behold a virgin shall conceive, and bear a son, and his name shall be called Emmanuel.
