Isaiah 51:12-52:12
This week's haftorah is the fourth of a series of seven "Haftarot of Consolation." These seven haftarot commence on the Shabbat following Tisha b'Av and continue until Rosh Hashanah.
The haftorahs of the past two weeks open with Israel's complaint that they have been abandoned by G‑d. Israel is not content with consolations offered by the prophets — instead they demand that G‑d alone comfort them. In response, this week's haftorah begins with G‑d's response: "I, indeed I, will comfort you."
After briefly reprimanding Israel for forgetting their Creator for fear of human and finite oppressors, the prophet describes the suffering and tribulations which Israel has endured. However, the time has arrived for the suffering to end. The time has come for Israel's oppressors to drink the "cup of suffering" which they had hitherto forced Israel to drink: "Awaken, awaken, put on your strength, O Zion; put on the garments of your beauty, Jerusalem the Holy City, for no longer shall the uncircumcised or the unclean continue to enter you. Shake yourselves from the dust, arise, sit down, O Jerusalem; free yourself of the bands of your neck, O captive daughter of Zion."
Isaiah extols the beauty of the messenger who will announce the good tidings of Redemption. "Burst out in song, sing together, O ruins of Jerusalem, for the L-rd has consoled His people; He has redeemed Jerusalem."
The haftorah ends by highlighting the difference between the Egyptian Exodus, when the Israelites hurried out of their exile and bondage, and the future Redemption: "For not with haste shall you go forth and not in a flurry of flight shall you go, for the L-rd goes before you, and your rear guard is the G‑d of Israel."

The next verse "13Behold My servant shall prosper; he shall be exalted and lifted up, and he shall be very high. יגהִנֵּ֥ה יַשְׂכִּ֖יל עַבְדִּ֑י יָר֧וּם וְנִשָּׂ֛א וְגָבַ֖הּ מְאֹֽד:
Behold My servant shall prosper: Behold, at the end of days, My servant, Jacob, [i.e.,] the righteous among him, shall prosper."
How does this & following relate to mercy & atonement?
The following verses speak of the outcome of atonement and repentance. After that, the Jewish People will arise once again and be respected among the nations. Just as they were once denigrated, to the same extent will they be revered. The next verses speak of the future redemption. See Rashi.
Could this be speaking about one person--Moshiach or someone else?
