Regarding John 21 and the Bible Wheel (see http://www.biblewheel.com/Collaboration/Tng_2003_06_13.asp), there is a relationship between the book of Jonah and John 21. Jonah allows himself to be cast into the sea, then is swallowed by a fish. Peter casts himself into the sea, then swallows some fish. The people of Ninevah don't know the difference between their right hand and their left hand, so Jonah has to tell them. The disciples don't know to fish on the right side of the boat, so Jesus has to tell them. There is also a discussion of whether Jonah should die, and whether the people of Ninevah should live, and a discussion of how Peter will die, and whether John should live.
