Due to his recruiting efforts in Casiphia (site unknown, probably a district of Babylon) 38 Levites and 220 temple servants joined the immigrants. One writer estimated the total number of men who returned with Ezra as about 1,700 plus women and children.118Another calculated the total number of men, women, and children as between 4,000 and 5,000.119
