There is nothing “Anti-Messiah” in the OT. If anything, there are Passages that relate to His Suffering (Isaiah 53, Psalm 22), His Substitutionary Atonement (Isaiah 53), His Miraculous Virgin Birth (Isaiah 7:14), His birth in Bethlehem (Micah 5:1), and that’s just off the top of my head. LOL! :-)
Exactly! I like the top of your head! :o)
