The whole company numbered 42,360, beside their 7.337 menservants and maidservants; and they also had 200 men and women singers. They had 736 horses, 245 mules, 435 camels and 6720 donkeys.
When they arrived at the house of the Lord in Jerusalem, some of the heads of the families gave freewill offerings toward the rebuilding of the house of God in its site. According to their ability they gave to the treasury for this work.
