Gen 49:8-10, Ruth 4:16-22, Mt 1:1-6

In the Old Testament, it was foretold that Christ would come as a descendant of Judah. In the Old Testament, it was foretold that Christ, who would come as a descendant of Judah, would play the role of a true king. (Deut 33:7, Gen 49:8-10)

Deut 33:7 And this is the blessing of Judah: and he said, Hear, Lord, the voice of Judah, and bring him unto his people: let his hands be sufficient for him; and be thou an help to him from his enemies.

Gen 49:8 Judah, thou art he whom thy brethren shall praise: thy hand shall be in the neck of thine enemies; thy father's children shall bow down before thee.

9 Judah is a lion's whelp: from the prey, my son, thou art gone up: he stooped down, he couched as a lion, and as an old lion; who shall rouse him up?

10 The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be.

As prophesied in the Old Testament, Jesus, the Christ, came as a descendant of Judah. (Ruth 4:16-22, Matthew 1:1-6,16)

Ruth 4:16 And Naomi took the child, and laid it in her bosom, and became nurse unto it. 17 And the women her neighbours gave it a name, saying, There is a son born to Naomi; and they called his name Obed: he is the father of Jesse, the father of David. 18 Now these are the generations of Pharez: Pharez begat Hezron, 19 And Hezron begat Ram, and Ram begat Amminadab, 20 And Amminadab begat Nahshon, and Nahshon begat Salmon, 21 And Salmon begat Boaz, and Boaz begat Obed, 22 And Obed begat Jesse, and Jesse begat David.

Matthew 1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham. 2 Abraham begat Isaac; and Isaac begat Jacob; and Jacob begat Judas and his brethren; 3 And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram; 4 And Aram begat Aminadab; and Aminadab begat Naasson; and Naasson begat Salmon; 5 And Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse; 6 And Jesse begat David the king; and David the king begat Solomon of her that had been the wife of Urias; 16 And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.
