John Wesley on Job 15:19

To whom - By the gracious gift of God: this he alleges to make their testimony more considerable, because these were no obscure men, but the most worthy and famous men in their ages; and to confute what Job had said, chap.9:24, that the earth was given into the hand of the wicked. By the earth he means the dominion and possession of it. Stranger - No person of a strange nation and disposition, or religion. Passed - Through their land, so as to disturb, or spoil them, as the Sabeans and Chaldeans did thee. God watched over those holy men so, that no enemy could invade them; and so he would have done over thee, if thou hadst been such an one.
