He stood to declare the Word near an inn door. Opposite him, on the other side of the road, were three trees growing at the side of a river. Soon after he had started preaching, a drunken man passed by who started shouting out at the end of every sentence from the preacher, ‘He’s lying!’ Dafydd Morris suffered this for a while, but as the man continued with his shouting and threatenings, his spirit was aroused, and he said to the crowd around him, ‘Listen! Those three trees will bear testimony against that man on Judgment Day, unless retribution overtakes him before then.’ The people noted his remark, and it was soon brought to their notice again, when the drunkard fell over a wall in his drunkenness one dark night, and was drowned. And this took place only a few paces away from the spot where the preacher had stood. As the Bible says, ‘Be not over much wicked, neither be thou foolish: why shouldest thou die before thy time?’
