Charles H. Spurgeon on Psalms 78:47

He destroyed their vines with hail. No more shall thy butler press the clusters into thy cup, O Pharaoh! The young fruit bearing shoots were broken off, the vintage failed. And their sycomore trees with frost. Frost was not usual, but Jehovah regards no laws of nature when men regard not his moral laws. The sycomore fig was perhaps more the fruit of the many than was the vine, therefore this judgment was meant to smite the poor, while the former fell most heavily upon the rich. Mark how the heavens obey their Lord and yield their stores of hail, and note how the fickle weather is equally subservient to the divine will.
