Where in the Bible does it mention reincarnation?

There is a life after death, and it doesn't say that there isn't in The Bible. If you look at the bible dictionary or the topical guide and look up death, you can find some places to go where it says that.

1John 5:11 The testimony is this: God has given us eternal life, and this life has its source in his Son.

1John 5:12 Whoever has the Son has this life; whoever does not have the Son of God does not have life.

1John 5:13 I am writing this to you so that you may know that you have eternal life---you that believe in the Son of God.
