Luke 22:31

Jesus apparently put Peter’s testing, which Jesus knew was coming in view of His own arrest and trials, in a cosmic setting because Satan was ultimately responsible. [Note: See Page, pp. 456-57.] Jesus viewed what would happen to Peter similarly to what had happened to Job (Job 1:6-7). Sifting as wheat pictures Satan’s attempt to separate Peter’s faithfulness to Jesus from him (cf. Job 1-2). The Greek word translated "you" (hymas) is in the plural indicating that Simon was not the only disciple whom Satan desired to sift. Probably Jesus used the name "Simon," Peter’s given Jewish name, because it pictured Peter in his natural state, not as Peter the rock. He probably repeated it in pathos anticipating the sad consequence of Satan’s testing.
