The number 320 has no well-established or prominent symbolic meaning in biblical or Jewish tradition, but appears as a specific population count in the lists of returnees.

320 is not a number that appears with special symbolic weight in the Bible or in classical Jewish numerology (gematria) in a widely recognized way. In the Bible, the number occurs in the lists of returnees after the Babylonian exile, where Harim's descendants are counted as 320 (Ezra 2:32; Nehemiah 7:35). This is a concrete demographic detail connected to the rebuilding of the Jewish community in Judah and does not give the number any deeper symbolic function. Although one can find Hebrew words or expressions corresponding to the numerical value 320 in gematria, this number does not have a fixed or well-known symbolic role like, for example, the numbers 7, 12, 40, or 613. It may still appear in specific kabbalistic or midrashic contexts, but without broad consensus on an unambiguous symbolic meaning.
