The bass next sings a secco recitative and arioso, the only components of the cantata in a minor key.
During this time, various tenors and basses sang with the group.
The bass sings in the voice of the Almighty, as quoted by the Archangel Raphael.
The bass as the vox Christi sings the words of Jesus.
