I hope that I can describe them so they make sense
49. James James
(The first James is large and in bold the 2nd James is smaller with two arrows one from the top and one from the bottom point at the m in he smaller James)
57. John
(In the centre of the square in bold with an arron top and bottom pointing at the capital J)
58. 2 3 5 7 11 13 17 19
I know that these are prime numbers but can't get the connection
49 James thye less ( a reference to the James that wasn't the Lord's brother.
57 - could be the Epistles (Letters) of john as appossed to the gospel of John.
could the numbers just refer to the book of Numbers in O.T?
