The number 68 has no prominent or well-established symbolic meaning in biblical or Jewish tradition.
The number 68 does not appear as an important symbolic number in the Bible or in classical Jewish tradition in the same way as numbers like 7, 12, 40, or 18. The most notable biblical occurrence is in 1 Chronicles 16:38, where Obed-Edom and his brothers numbered sixty-eight and were appointed to serve at the house of the Lord. Beyond this specific instance, the number has no established independent symbolic role in biblical or Jewish tradition compared to more central numbers. Through gematria, the Hebrew word חַיִּים (chayyim, 'life') can be calculated to have the numerical value of 68 (ח=8, י=10, י=10, ם=40). However, this connection is far less known than the number 18, which corresponds to חַי (chai, 'living') and has become a widely recognized symbol in Jewish culture. Obed-Edom, son of Jeduthun, and his brothers made up the total of sixty-eight who, together with Hosa, served as gatekeepers. This was part of David's organization of temple service after the ark of the covenant was brought to Jerusalem.*
