Curse and Healing of Horses During Zion's Camp

“We warned them, in the name of the Lord, to stop their murmuring; for, if they did not, the displeasure of the Almighty would be manifested in judgments in their midst. But the majority of them paid no attention to what we said, until one morning when they went out to harness up their horses, and found them all so lame as to be unable to travel. We told them that this was a curse which had come upon them because of transgression; but, if they would repent, it might be removed—if not, a greater curse would come upon them. They believed what we said, and repented of their folly. The consequence was, we were soon on our journey again. — Lucy Mack Smith, History of Joseph Smith by His Mother, Chapter XLII”
