"LAVAN" or "LABAN" is Latinized form of the Hebrew word "לבן", which means "WHITE". The first 7 Capital letters form this word when you add up the first 3 to equal "L". Forrest does similar 3 to 1 grouping of letters in his master blueprint of his poem related to the Fib Sequence as well. Note that 11 is "L" when the "J" is skipped in the alphabet and is consistent with all other ciphers involving this poem thus far.
In last post in this forum, I showed that the first 7 lines of Forrest Fenn's Treasure Poem is the Hebrew Word for "WHITE". This was a +1 skip between lines of the poem. Now, I show you a +9 skip that is the Hebrew word for "BLACK". It would be quite the coincidence that there is 7 numbers between a +1 and +9. There is also 7 colors of the rainbow. Because of this, I've spent a bit of time looking for the other Hebrew words for the colors of the rainbow in the same manner that I found Black and White, but have no success yet. Perhaps you can figure it out and share with us.
