The number of descendants of Bebai who returned from exile in Babylon
The number 623 is mentioned in Ezra 2:11 as the count of descendants of Bebai who returned to Judah after the Babylonian exile. This census list in Ezra 2 documents those who returned under Zerubbabel's leadership and provides a detailed picture of the rebuilding of the Jewish community after captivity. The family of Bebai is also mentioned in Nehemiah 7:16, but there with the number 628, which may reflect different times of registration or variations in textual transmission. Beyond this specific historical occurrence, the number 623 has no prominent symbolic meaning in biblical or Jewish tradition. The nearby number 613 holds great significance in Jewish tradition as the traditional count of mitzvot (commandments) in the Torah, a view dating back to the Babylonian Talmud (Makkot 23b). The difference between the figure 623 in Ezra 2:11 and 628 in Nehemiah 7:16 regarding Bebai's descendants is a well-known example of numerical variations between parallel census lists in Ezra and Nehemiah, and has been the subject of textual-critical discussion. Through gematria (Jewish numerology), one can calculate values for Hebrew words that sum to 623, but there is no widely recognized or traditional interpretation specifically linked to this number.*
