What is the connection between ’etsem, “bone,” and ’atsma’ut, “independence”? The root ’-S-m basically means “to be strong, mighty, numerous” (mentioned many times in reference to the children of Israel in Exodus and in the haggadah); hence the meaning “bone,” which is strong, firm, the “backbone” of our body (compared to the soft flesh). This led to the meanings “essence,” “entity,” “oneself,” “independence,” etc.
