Isaiah 53

“Chapters 52-53 [of Isaiah] reveal how the arm of the LORD triumphs ironically through the suffering of the servant on behalf of the rest of the community and, according to 52:13-15, even those outside the Jewish community. In Isaiah 54, Zion is called to burst into song and shout for joy, the same response demanded when the arm of the LORD worked salvation in 52:7-10. With chap. 55, however, 'the segment culminates in the great invitation to participate in a renewal covenant,' that is to respond to God's salvation of the servant who has borne the sin of the people (Oswalt 1997: 10).”—A Severe Mercy, page 211
