The Haftarah for Parashat Ki Teitzei is drawn from Isaiah 54:1–10, a passage that contains a lot of imagery concerning restoration, covenantal fidelity, and the unshakeable mercy of Mar-Yah toward His people. The reading follows the great Servant Song of Isaiah 53, where the Suffering Servant bears the sins of many. Thus Isaiah 54 is a natural continuation, presenting the results of that redemptive act – joy, expansion, and everlasting love.
The Barren One Shall Sing (verses 1-3)
“Rejoice, you who are barren…break forth and cry, you that do not travail: for the children of the desolate are more than the children of her that has a husband: for Mar-Yah has said, Enlarge the place of your tent, and of your curtains, fix them: spare not, lengthen your cords, and strengthen your pins; spread forth yet on the right and left: and your seed shall inherit the Gentiles, and they shall make the desolate cities to be inhabited.”
