What does Ezra 2:19 mean?

The children of Hashum, two hundred twenty and three, are counted. This modest group adds to the overall total and reinforces that many families, not only the largest, took part in the return. Their listing secures their place in the community’s legal and social framework, a necessity for fair distribution of land and duties. The steady march of such entries underlines the seriousness and orderliness of the restoration after exile, where identity had to be clearly reestablished for the sake of unity, justice, and the future worship that would again center in Jerusalem.
