Luke 22:31-32

"Simon, Simon, Satan has asked to sift you as wheat. But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers.

Simon, Simon, Satan has asked
Job 1:6-12 One day the angels came to present themselves before the LORD, and Satan also came with them. The LORD said to Satan, "Where have you come from?" Satan answered the LORD, "From roaming through the earth and going back and forth in it." Then the LORD said to Satan, "Have you considered my servant Job? There is no one on earth like him; he is blameless and upright, a man who fears God and shuns evil." "Does Job fear God for nothing?" Satan replied. "Have you not put a hedge around him and his household and everything he has? You have blessed the work of his hands, so that his flocks and herds are spread throughout the land. But stretch out your hand and strike everything he has, and he will surely curse you to your face." The LORD said to Satan, "Very well, then, everything he has is in your hands, but on the man himself do not lay a finger." Then Satan went out from the presence of the LORD.

to sift as wheat
Amos 9:9 "For I will give the command, and I will shake the house of Israel among all the nations as a grain is shaken in a sieve, and not a pebble will reach the ground."

But I have prayed for you, Simon
John 17:9 "I pray for them. I am not praying for the world, but for those you have given me, for they are yours."
John 17:15 "My prayer is not that you take them out of the world but that you protect them from the evil one."
Romans 8:34 Who is he that condemns? Christ Jesus, who died--more than that, who was raised to life--is at the right hand of God and is also interceding for us.

And when you have turned back, strengthen your brothers
John 21:15-16 When they had finished eating, Jesus said to Simon Peter, "Simon son of John, do you truly love me more than these?" "Yes, Lord," he said, "you know that I love you." Jesus said, "Feed my lambs." Again Jesus said, "Simon son of John, do you truly love me?" He answered, "Yes, Lord, you know that I love you." Jesus said, "Take care of my sheep." (Also verse 17)
