Bamidbar 2:1-3

Orthodox Jewish Bible

2 And Hashem spoke unto Moshe and unto Aharon, saying,

² The Bnei Yisroel shall encamp, each man under his own degel (standard, banner), with the otot (ensigns) of the bais of their avot; some distance from it, around the Ohel Mo’ed must they encamp. [see Yehoshua 3:4]

³ And on the east side toward the rising of the sun shall they of the degel (standard, banner) of the machaneh of Yehudah encamp by their tzvaos: and Nachshon ben Amminadav shall be Nasi of the Bnei Yehudah.[Bereshis 49:10]
