What is one of the significant themes of the 'suffering servant' passages in Isaiah 53?

A They primarily served to console the exiles in Babylon, offering hope of eventual restoration to their homeland. B They presented the idea of a servant who suffers on behalf of others, highlighting themes of vicarious suffering and redemption. C They reflected a critique of the Babylonian gods and their inability to save. D They were primarily intended to legitimize the political leadership of the Davidic line.
