Numbers 2:1-3

American Standard Version

2 And Jehovah spake unto Moses and unto Aaron, saying, ² The children of Israel shall encamp every man by his own standard, with the ensigns of their fathers’ houses: over against the tent of meeting shall they encamp round about. ³ And those that encamp on the east side toward the sunrising shall be they of the standard of the camp of Judah, according to their hosts: and the prince of the children of Judah shall be Nahshon the son of Amminadab.
