The Bible does not specifically mention Peter being crucified upside down. However, a tradition in early Christian writings attributes Peter's crucifixion in this manner as a request of his own, considering himself unworthy to die in the same way as Jesus. This tradition is found in texts outside of the Bible.
The Bible does not say how or when Peter died, but it is most unlikely that he died by being crucified upside down.
The tradition about Peter's death began when the venerable Polycarp of Smyrna had tried to win an argument with the mid-second century pope Anicetus (156-166) on a matter of theology, by saying that he spoke with the authority of the apostle John. In response, Anicetus said that Peter was beheaded by Nero in Rome and that he spoke with the authority of Peter. In this first mention of Peter's death, he was beheaded, not crucified. Then in the third century, the Church Father Origen changed the story somewhat, saying that Peter, condemned to crucifixion, felt himself unworthy to be crucified the same way as his Lord, and so chose crucifixion upside down.
The Bible version used is usually in parenthesis after listing the verse. In this case it would be 1 Peter 13 (KJV).
Luke 9:20.
2 peter chapter2 verse 4.
As a starting point you could refer to 2 Peter 1:21.
1 Peter 4:11
There is no direct reference in the bible to Simon Peter being crucified. The two references to his death are in John 21:19 where Peter asked Jesus how he would die. The bible does not record Jesus' response. The second reference, which is where Catholic historians draw a reference to crucifixion is in the previous verse (John 21:18) which prompted Peter to ask Jesus about his manner of death. ("when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.") Some feel that the reference to outstretched hands is referring to crucifixion.
Matthew chapter 4 verse 18
There is no scripture reference that places Peter in Rome. Any such evidences are outside the Bible.
Luke 4:31-39 and parallel passages tell us that Peter's home-town was Capernaum.
Seven times: Ecclesiastes 2 verses, Isaiah 2 verses , Acts 1 verse, Romans 1 verse, 1 Peter 1 verse
You'll need to be more specific to find the verse of what you are looking for because Jesus is explaining things to thousands of men and women before he was crucified. 'What was being explained' would be a helpful question to start with.
No direct quotation, but it's implied in 1 Peter 3 verse 3 and 1 Timothy 2 verse 9.
