Charles H. Spurgeon on Psalms 78:65

The Lord awaked as one out of sleep. Justly inactive, he had suffered the enemy to triumph, his ark to be captured, and his people to be slain; but now he arouses himself, his heart is full of pity for his chosen, and anger against the insulting foe. Woe to thee, O Philistia, now thou shalt feel the weight of his right hand! Waking and putting forth strength like a man who has taken a refreshing draught, the Lord is said to be, like a mighty man that shouteth by reason of wine. Strong and full of energy the Lord dashed upon his foes, and made them stagger beneath his blows. His ark from city to city went as an avenger rather than as a trophy, and in every place the false gods fell helplessly before it.
