This haftarah opens answering a specific complaint Isaiah attributes to Israel, that their way is hidden from God and their claim overlooked by Him, met with the reassurance that the everlasting God, creator of the ends of the earth, does not faint or grow weary, and that those who wait on Him will renew their strength and rise on wings like eagles.
The passage then turns to a figure stirred up from the east, called in righteousness to God's service, given victory over nations and kings, a figure the passage treats as evidence of God's command over history rather than naming at length. Shortly after, the text addresses Israel directly as God's servant, Jacob whom He has chosen, the offspring of Abraham, God's friend, taken from the ends of the earth and reassured not to fear, since God has chosen them and not cast them off.
The haftarah closes with agricultural imagery, Israel made into a sharp new threshing instrument able to thresh mountains and hills, an image of a formerly weak people given the strength to accomplish what had seemed impossible.
The reassurance that God has chosen Israel and not cast them off closes the haftarah on the same note it opened with, a people convinced their situation has been overlooked answered directly with evidence that their history has in fact been guided deliberately from its very first called ancestor onward.
