If you divide 53 into 159 you will see that it divides evenly 3 times, i.e., with a matrix width of 53 characters, a code at a skip of 159 characters will occur on every third line. If you will look at the list of Bonnie's codes found in this area, all of the codes in this matrix occur either at multiples of 53 or a bare minimum of one to two skips. This was done so they will all appear on either horizontal or vertical lines. However, it does indicate these codes may have been chosen to provide the most convincing array and not necessarily what is really encoded in this passage. According to scripture there is only one Bride of Christ, one trumpet and one deliverance of the Bride.
Lets look at some of the facts.
A search was performed on the following words utilizing the whole of the Torah and this time limiting the skip to 250 because these words have up to 5 letters. The word Rapture occurs about 243 times. 1st Tishri occurs about 275 times. The year 5760 occurs about 258 times. It is also possible that other word choices, or spellings could be used.
