Very convincing to me that John is the other witness rather than Enoch
(All this time been thinking Elijah and Enoch only two translated) -
also would like to add this scripture below. John wrote of himself
that Jesus said about him concerning his "will that he tarry till I come".

Of course let's seek the Holy Spirit confirmation for this inspiration.

Joh 21:20-24

(20)Then Peter, turning about, seeth the disciple whom Jesus loved
following; which also leaned on his breast at supper, and said, Lord,
which is he that betrayeth thee?

(21)Peter seeing him saith to Jesus, Lord, and what /shall/ this man
/do?/

(22)Jesus saith unto him, If I will that he tarry till I come, what
/is that/ to thee? follow thou me.

(23)Then went this saying abroad among the brethren, that that
disciple should not die: yet Jesus said not unto him, He shall not
die; but, If I will that he tarry till I come, what /is that/ to thee?

(24)This is the disciple which testifieth of these things, and wrote
these things: and we know that his testimony is true.
