Here are the missing sources for yesterday’s post:
Gematria linking the measurement’s of Noah’s ark — including its 30-cubit height — to the four-letter name of God, YHVH, is credited to the 16th Century Kabbalist Isaac Luria, AKA “the Ari.” I do not have an exact citation, and perhaps there is an older source as well.
Yalkut Reuveni, a 17th Century anthology of writings from kabbalist Reuben Kahana of Prague, is credited with linking Proverbs 18:10 with Noah entering the ark.
Kabbalists, including the 18th Century Levi Yitzhak of Berditchev, also offer commentary linking Noah’s ark [teva] and the concept of ‘word’ (‘teva‘ can also mean ‘word’). This commentary thread focuses on the power and responsibility of language and thought.
