Would you happen to know off the top of your head which scriptures in the Old Testiment specifically contain GODS words regarding the Messiah to come?
According to someone's rule, I know I'm not supposed to answer a question with a question, but what do you mean by GODS words? The Old Testament is God's Word, all of it.
Isaiah 53 is generally taken as words speaking of Messiah. Many of the Psalms are Messianic; 2, 23, 24, 40, 72, 89, 91, 110, and more.
