Numbers Chapter 2 World English Bible
Those who encamp on the east side toward the sunrise shall be of the standard of the camp of Judah, according to their divisions: and the prince of the children of Judah shall be Nahshon the son of Amminadab.
These are those who were numbered of the children of Israel by their fathers' houses. All who were numbered of the camps according to their hosts were six hundred three thousand five hundred fifty.
Thus the children of Israel did. According to all that Yahweh commanded Moses, so they encamped by their standards, and so they set out, everyone by their families, according to their fathers' houses.
