Canon Four: Generally speaking, the reading that explains all the variants is most likely the original one. Reason: Words or even letters can look alike and the CONTEXT of the word/letter should indicate which is closest to the original. Example: A waw looks like a "7"; a yodh looks like a "7" with only half a stem. You can only imagine how mistaking one for the other could change a word. (Speaking of "7", I have had mine mistaken for a "1" and a "9". So I've adopted the European method of a slash through the stem.) Thoughts?
