WASHINGTON (AP) -- National Geographic unveiled an ancient manuscript Thursday that may shed new light on the relationship between Jesus and Judas, the disciple who betrayed him.

The papyrus manuscript was written probably around 300 A.D. in Coptic script, a copy of an earlier Greek manuscript.

It was discovered in the desert in Egypt in the 1970s and has now been authenticated by carbon dating and studied and translated by biblical scholars, National Geographic announced.

Unlike the four gospels in the Bible, this text indicates that Judas betrayed Jesus at Jesus' request.

The text begins "the secret account of the revelation that Jesus spoke in conversation with Judas Iscariot."

The key passage comes when Jesus tells Judas "you will exceed all of them. For you will sacrifice the man that clothed me."
