Psalms 18:9 - Exposition

He bowed the heavens also, and came down (comp. Psalms 145:5 ). In a storm the clouds do actually descend, and the whole heaven seems to be bowed down to earth. God is said to "come down" to earth whenever he delivers the oppressed, and takes vengeance on their oppressors (see Exodus 3:8 ; 2 Samuel 22:10 ; Psalms 144:5 ; Isaiah 64:1-12 . I, 3, etc.). And darkness was under his feet. A deep darkness commonly accompanies both earthquake and storm. When God actually descended on Mount Sinai, it was amid thunders and lightnings, and "a thick cloud" ( Exodus 19:16 ), elsewhere called "thick darkness" ( Deuteronomy 5:22 ).
