Isaiah 54:6

For the Lord hath called thee. — The words find their explanation, perhaps their starting-point, in the history of Hosea and Gomer (Hosea 1-3). The husband has punished the faithless wife by what seemed a divorce, but his heart yearns after her, and he takes her back again.

When thou wast refused. — Some critics render Can she be rejected ...? with the implied answer. “No, that is impossible,” but the Authorised version is tenable, and gives an adequate meaning.
