There are many prophecies in the Bible which Christians believe came true. Many completed prophecies have historical facts to prove their validity.
Genesis 16 in the Bible tells of the Jews and the Arabs. Abraham and his wife Sarah could not have children, so Sarah convinced Abraham to conceive with her maid servant Hagar. Hagar gave birth to a son named Ishmael. Abraham and Sarah later had another son named Isaac.
Genesis 16:12 says “He (Ishmael) will live in hostility toward all his brothers.” Ishmael is widely accepted by Arabs as their ancestor, and Isaac is accepted by the Jews to be their ancestor. This is partly why there is animosity between the Arabs and Jews in the Middle East to this day, because both believe that their ancestor is the chosen one by God.
There are many other prophecies in the Bible, some Bible scholars suggest that there are over 300 prophecies about Jesus that came true. Many are small details, like his birthplace, lineage, and death.
Matthew 1:1–17 gives the geneology (family lineage) of Jesus. It starts with Abraham. Other passages in the Bible detail the lineage from Adam to Abraham. Matthew 1 lists the genealogy of Jesus through Abraham, Isaac, Jacob, Judah, then through David, then finally Jesus.
Genesis 49:10 says that “The scepter will not depart from Judah.”, meaning that Jesus is descended from Jacob’s son Judah, originator of one of the twelve tribes of Israel.
2 Samuel 7:12-13 says (talking about King David) “I will raise up your offspring to succeed you, your own flesh and blood, and I will establish his kingdom. He is the one who will build a house for my name, and I will establish the throne of his kingdom forever.”
