Isaiah 28:20

For the bed is shorter ... -This is evidently a proverbial saying, and means that they would find all their places of defense insufficient to secure them. They seek repose and security - as a man lies down to rest at night. But they find neither. His bed furnishes no rest; his scanty covering furnishes no security from the chills of the night. So it would be with those who sought protection in idols, in the promises of false prophets, and in the aid which might be obtained from Egypt. So it is with sinners. Their vain refuges shall not shield them.
