Ezra 2:21ESV·traditional attribution

The sons of Bethlehem, 123.

Matthew Henry Presbyterian @wholebiblehenry

We may observe here, 1. That an account was kept in writing of the families that came up out of captivity, and the numbers of each family. This was done for their honour, as part of their recompence for their faith and courage, their confidence in God and their affection to their own land, and to stir up others to follow their good example.
