Isaiah 41-43
In Isaiah 41 the Lord foretells of things to come in Judah, and speaks of a king that He has called, but who He does not name. Many Christian scholars believe that God is referring to Cyrus, whom He will name in Isaiah 44 and 45, who will rule among the Medes and Persians after the Babylonians are conquered. In 42 the Lord is talking about another King to Come, Who will be Jesus Christ, with several things written here that were prophetic of, and fulfilled in Him.
In chapter 43 the Lord predicts the future time when He will bring together His people from out of all the nations of the world, which was at least partially fulfilled following WWII, when Israel became a recognized nation in May of 1948. God will never go back on His promises to Abraham, and will always maintain a remnant in Israel, even though satan will not stop in trying to wipe them out.
