Philoxenus of Mabbug

And the nature of the fear of God is that it urgeth us [to do] one thing, and one thing only, for it stirreth us up to do all the commandments, and for this reason the Spirit of God desired to teach us the fear of God by the hand of all the Prophets. And the Prophet David himself said, "All those who pass over the earth shall fear the Lord, and all those who go down into the dust shall kneel [before Him]."
