Haftaras Shemos (Ashkenazic custom, Isaiah 27:6-28:13, 29:22-23)
Like the exile-experience of Egypt, the Haftarah begins with .Jacob as the root of the eventual triumph that will lead to a flourishing, world-renowned and respected "Israel." "Jacob" always symbolizes the Jewish people in its time of travail and degradation, before it succeeds in realizing the goals and potential represented by "Israel," just as the very name was given to Jacob in recognition of his enhanced stature.
The prophet Isaiah lived in a time of turmoil, when the kingdom of the Ten Tribes was hurtling downhill in its spiritual decay, with defeat and exile on the way, and the Davidic kingdom of Judah, too, was suffering from spiritual decline. In this Haftarah, Isaiah depicts the failures of both kingdoms. He begins with the encouraging prophecy that the "root" of Jacob - like all roots, unseen. In the ground and trampled upon by those who walk obliviously over it - will once more produce luxuriant produce. Isaiah points out that, despite the Divine wrath visited upon the Jewish people often in their history, they have not been decimated as have various other nations. Those who struck Israel were punished more, while the Jewish people survive and will rise again, its sins being atoned for in the physical destruction of its fields and cities. But, although G-d preserves the root, the nation has forfeited its right to His manifest mercy because of its failure to recognize its true role in the world. Nevertheless, when the time comes, G-d will "thresh" the world to find the scattered kernels of His still beloved people.
Then Isaiah goes on to the doomed Ten Tribes, led by Ephraim. The simile for them is arrogance and drunkenness, both of which prevent people from recognizing the truth and acting upon it. The result is that heads, which are so pampered with luxuries that they are like a valley of oil, will lose their crowns and their glory.
But Isaiah is far from content with the masses of Judah. They have become so estranged from the authenticity of the Torah and its wisdom that they must be spoon fed – a commandment at a time, and a "measuring line" at a time. (The "line" is used by builders to make sure their bricks are properly aligned; this symbolizes the guidelines to behavior.)
As always, the Haftarah ends with words of comfort and encouragement, in this case skipping to the next chapter of Isaiah for its two concluding verses.
