D&C 9
Oliver had the gift to translate but he did not realize how hard the exercise of that gift would be. He chose to fall back to being a scribe for Joseph and the window closed. The Lord declared that at this time it was expedient for Oliver to only serve as scribe and not to try returning to translation. Perhaps the work would have been fast with Joseph copying the characters and Oliver translating those copies than it was with Joseph translating and Oliver transcribing the oral translation. I love how the Lord explicitly told them that neither of them was under condemnation for the failed effort. Coming relatively soon after the loss of the 116 pages Joseph might have been very sensitive about that.
