David evidently saw the storm first over a large body of water, perhaps the Mediterranean Sea. He spoke of the thunder as God"s voice. This is an apt comparison, since thunder is a noise that comes from "heaven," i.e, the sky. However, he may also have used this figure to imply Yahweh"s control over His creation. God brought the creation into existence with a word ( Genesis 1:3; Genesis 1:6; Genesis 1:9; Genesis 1:14; Genesis 1:20; Genesis 1:24). [source][source][source]
