Numbers 10:14

10:14 The standard ¹  of the camp of the Judahites set out first according to their companies, and over his company was Nahshon son of Amminadab.

Numbers 10:22

10:22 And the standard of the camp of the Ephraimites set out according to their companies; over his company was Elishama son of Ammihud.

¹ sn The “standard” (דֶּגֶל, degel) was apparently some kind of a symbol put up on a pole to signify the tribal hosts. R. de Vaux thought it simply referred to a pole or a mast, but that would not distinguish tribes (Ancient Israel, 226-27).
