Some do and some don’t. Apparently they do not accept their own scriptures regarding the signs of the Messiah. Many even chose to completely disregard portions of scripture such as Isaiah 53 and exclude it from their texts.
Therefore, since we have such a hope, we are very bold. 13 We are not like Moses, who would put a veil over his face to keep the Israelites from gazing at it while the radiance was fading away. 14 But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away. 15 Even to this day when Moses is read, a veil covers their hearts. 16 But whenever anyone turns to the Lord, the veil is taken away. 17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 18 And we, who with unveiled faces all reflect the Lord’s glory, are being transformed into his likeness with ever-increasing glory, which comes from the Lord, who is the Spirit.
2nd Corinthians 3:12-18
Isaiah 7:14 Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and will call him Immanuel.
Matthew 1:23 “The virgin will be with child and will give birth to a son, and they will call him Immanuel” –which means, “God with us.”
