This week's haftorah is the third of a series of seven "haftarot of Consolation." These seven haftarot commence on the Shabbat following Tisha b'Av and continue until Rosh Hashanah.
G‑d addresses the "afflicted and storm-tossed" Jerusalem "who has not been
comforted," assuring her that she, and her people, will be restored to full
glory. The foundation, walls and ground of Jerusalem will be laid with precious
stones. Her children will be "disciples of the L-rd," and will enjoy abundant
peace. Any weapon engineered against her will fail.
The prophet then invites the thirsty to acquire "water," namely those who are
thirsty for spirituality should study the quenching words of Torah. He promises
the nation an everlasting covenant similar to that made with King David. This is
also an allusion to the Messiah, David's descendant, who will be revered by all
of the nations of the world.
