Thanks, Tom. I had never looked at that in hebrew before. And in the first hebrew line I find one more pertinent cycling reference.

The phrase "under heaven" in hebrew is "תַּ֥חַת הַשָּׁמָֽיִם"/"tachat ha-shamayim". The word ta-chat means"under" or "bottom", and in the european (ashkenaz) dialect it is pronounced ta-chas, which then becomes the Yiddish word tuchus (or toochis/tookis) which means butt or derriere.

And that is a big "under"-lying issue for many cyclists.
