Editing Bible code (section)

===Early history===
The 13th-century Spanish [[rabbi]] [[Bachya ben Asher]] described an ELS in the Bible. His four-letter example related to the traditional zero-point of the [[Hebrew calendar]]. Over the following centuries there are hints that the ELS technique was known, e.g. in [[Pardes Rimonim]] of the 16th century mystic [[Moshe Cordovero]].<ref>{{cite web |url=https://aish.com/torah-codes-explained/ |title=Torah Codes Explained|date=August 2, 2011 }}</ref><ref>{{cite web |url=https://www.torchweb.org/torah_detail.php?id=90 |title=The Rambam and the Bible Codes}}</ref>

In the 20th century, many examples were found by [[Michael Ber Weissmandl]] and published by his students after his death in 1957. In the 1980s,  some discoveries of Israeli school teacher Avraham Oren came to the attention of the mathematician [[Eliyahu Rips]] at the [[Hebrew University]] of Jerusalem. Rips then took up the study together with his religious studies partners [[Doron Witztum]] and Alexander Rotenberg, among several others.
