Job 1:7

From going to and fro As the word is used by the Satan of himself there is, naturally, no shade of self-condemnation in it: rather the reverse, he speaks with a certain consciousness of his assiduous faithfulness. The term is used of "the eyes of the Lord, that go to and fro," 2 Chronicles 16:9. What is suggested is the swiftness and ubiquity of his survey of men. Similarly walking up and downis said of those benevolent emissaries sent forth from heaven in the interest of the suffering righteous of the earth, Zechariah 1:10-11; Zechariah 6:7. The growing light of revelation cast the figure of Satan into deeper shade, and his restless activity receives a corresponding deepness of tint, "Your adversary, as a roaring lion, walketh about, seeking whom he may devour," 1 Peter 5:8.
