Repairers of the Breach
Both Ezra and Nehemiah are defined in Scripture as examples of Yahuwah's faithful at the very end of time. It was these men that were led by the Spirit of Yahuwah to rebuild not only the physical walls of Jerusalem, but more importantly they were called to restore to Israel the oracles of truth that had been lost during their unfaithfulness and captivity in Babylon.
Just as the Heavenly Father called them out of physical Babylon to return to Jerusalem and His truths, so He is calling this last generation of faithful out of "spiritual Babylon," false beliefs and traditions of men. He is appointing them to be repairers of the breach in His divine and ordained laws, as well as units of time according to His lunisolar calendar. The Jerusalem they are focused on is not the earthly; the one made with hands, but rather they shall be rewarded with the heavenly New Jerusalem, which is not made with hands.
