The phrase "restore the fortunes" (shuv shebut) is one of Scripture's great restoration formulas. When Job's fortunes were restored (shebut, Job 42:10), when the exiles returned from Babylon (Psalm 126:1), when God promises to restore Judah (Joel 3:1) — all use this concept. Shebut captures the eschatological hope that God's ultimate word is not captivity but homecoming, not loss but restoration, not exile but return.
Shebut (also spelled shevut) refers to captivity or the reversal of captivity — the "turning of the fortunes." It is a profound word of reversal: what was taken is returned, the exiled come home, the crushed are restored.
