A Sheep sheltered under a Bramble during a storm and fell asleep. On waking the Sheep found itself snared by the Bramble. Protection and fleece gone!
Protection can be fleeting.
A Sheep, during a severe storm, wandered into a thicket for shelter, and there lay so snug and warm that he soon fell fast asleep. The clouds clearing away, and the winds returning to rest, inclined the Sheep to return to his pasture. But, ah! what was his situation: a Bramble had laid such a firm hold of his fleece, that it was left as a forfeit for the protection the thicket had given him.
