And the Lord said to Satan, “From where do you come?” So Satan answered the Lord and said, “From going to and fro on the earth, and from walking back and forth on it.” (Job 1:7 NKJV)

Satan, whose name means “Accuser,” appears prominently in the book of Job. When God asked him from where he had come, Satan answered, “From going to and fro on the earth.” This response described his wandering existence since being cast down from heaven. So filled with rage and restlessness against God, he continually circles the earth like a lion looking for prey, desiring to destroy those whom God loves. This is why the apostle Peter wrote, “Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour” (1 Peter 5:8).
