The curse that the Lord is referring to can be found in Deuteronomy 28th chapter verses 15 through the end of the chapter. Who are the reproaches that the Lord gave Israel to? "And now have I given all these lands into the hand of Nebuchadnezzar the king of Babylon, my servant; and the beasts of the field have I given him also to serve him. And all nations shall serve him, and his son, and his son's son, until the very time of his land come: and then many nations and great kings shall serve themselves of him.” (Jeremiah 27: 6-7)
Not only did Israel have to serve Nebuchadnezzar for their transgressions, but also all nations had to serve him, and his son, and his son's son. As I stated earlier, as Israel goes, so goes the whole world. Who is Nebuchadnezzar and his sons? Nebuchadnezzar was the first Gentile world ruler and his kingdom was Babylon, which was represented by a Lion. Then followed the Medes and Persians (modern day Russia and Iran) which was represented by a Bear. Then followed the Greeks, which is represented by the Leopard. Then finally came Rome, which is currently in control of the world now and is represented as the wild beast or terrible beast. "Therefore I will be unto them as a lion: as a leopard by the way will I observe them: I will meet them as a bear that is bereaved of her whelps, and will rend the caul of their heart, and there will I devour them like a lion: the wild beast shall tear them. O Israel, thou hast destroyed thyself; but in me is thine help. I will be thy king: where is any other that may save thee in all thy cities? and thy judges of whom thou saidst, Give me a king and princes? I gave thee a king in mine anger, and took him away in my wrath.” (Hosea 13: 7-11)
Jesus is the king of Israel, “And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth, to a virgin espoused to a man whose name was Joseph, of the house of David; and the virgins' name was Mary. And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women. And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be. And the angel said unto her, “Fear not, Mary: for thou hast found favour with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob forever; and of his kingdom there shall be no end.” (St. Luke 1: 26-33)
