Isaiah 51: 1-3.
Hearken to Me, ye that follow after righteousness, ye that seek the Lord: look unto the rock whence ye are hewn, and to the hole of the pit whence ye are digged.
2 Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him.
3 For the Lord shall comfort Zion: He will comfort all her waste places; and He will make her wilderness like Eden, and her desert like the garden of the Lord; joy and gladness shall be found therein, thanksgiving, and the voice of melody.
In the next several verses, we will see a call to righteousness alternated with comfort for the righteous.
In this first one, Jehovah pleads with His people who do pursue righteousness to pay attention, listen to what He says. Then He reminds them of Abraham and Sara, calling them “the rock” from which Israelis quarried. The same God Who created a great nation from Abraham and Sara can restore and comfort Israel again.
The God Who created a great nation, through the miracle of Isaac’s birth, could again make Israel a great nation. Looking at the world situation today, it is clear that it will take another miracle of God to fulfill His promise to restore His people. God had called Abraham alone, and blessed him. He can, and will, restore His people
There is some teaching out there that Judah refers only to Jerusalem, Zion, and that the other ten tribes are not mentioned; therefore, they will be destroyed. This is very hard to support biblically. The name Judah has historically stood for all twelve tribes. The entire nation will be restored, not just Judah as a tribe, but Judah as it stands for all Israelites.
In verse 3, we see that not only will the original contracts with God and Jerusalem and Zion be comforted; all the waste places, of all the land ruled by Judah and the Messiah of the house of David will be comforted and blossom as a rose, like the garden of Eden.
These prophecies are yet to be fulfilled during the Millennium, although there is already a reclaiming of land that had gone barren and is now thriving and producing much food.
