Jamieson-Fausset-Brown Bible Commentary

children of Arah, seven hundred seventy and five--The number is stated in Neh 7:10 to have been only six hundred fifty-two. It is probable that all mentioned as belonging to this family repaired to the general place of rendezvous, or had enrolled their names at first as intending to go; but in the interval of preparation, some died, others were prevented by sickness or insurmountable obstacles, so that ultimately no more than six hundred fifty-two came to Jerusalem.
