Commentaries:
These verses give us a sense of God's feeling after patiently waiting for necessary developments to occur. The psalmist pictures Him waiting, seemingly asleep and unaware. But suddenly He roars into action, releasing a pent-up, emotional shout like a mighty warrior exhilarated by anger and the effects of alcohol. Things happen quickly and dramatically when God decides to act!
