Matthew Henry on Ezra 8:1-20
Ezra, having received his commission from the king, beats up for volunteers, as it were, sets up an ensign to assemble the outcasts of Israel and the dispersed of Judah, Isa 11:12. "Whoever of the sons of Sion, that swell with the daughters of Babylon, is disposed to go to Jerusalem, now that the temple there is finished and the temple-service set a-going, now is their time."
