9:6 thou hast made heaven. This is one of the great affirmations of faith in Scripture, recognizing publicly that the God of Israel was, first of all, the Creator of the entire cosmos and everything in it, a concept utterly foreign to the pagan religions of other nations.

9:6 thou preservest them. Not only is God the Creator of all things, but also their Sustainer (compare Colossians 1:16-17; Hebrews 1:2-3). This principle of universal conservation of the created universe is recognized scientifically in the most basic of all scientific laws, the Law of Conservation of Mass and Energy.

9:6 host of heaven. The host of heaven consists of the angelic creation. Some of these had rebelled against their Creator, but most still worship Him.
