David praised God for His awesome power as a consequence of observing a severe thunderstorm either truly or in his mind's eye. Israel's pagan neighbors gave the credit for storms and other natural phenomena to their gods. Consequently this psalm was a polemic against belief in these idols as well as a tribute to the uniqueness of Yahweh.
"Whether David was building the psalm out of an ancient fragment, or turning to a style that would recall the old battle-hymns of God's salvation, the primitive vigour of the verse, with its eighteen reiterations of the name Yahweh (the Lord), wonderfully matches the theme, while the structure of the poem averts the danger of monotony by its movement from heaven to earth, but the path of the storm and by the final transition from nature in uproar to the people of God in peace."77
