Numbers 26:22

26:22 These were the families of Judah according to those numbered of them, 76,500. ³ 

[7:12]  ¹ sn The tribe of Judah is listed first. It seems that it had already achieved a place of prominence based on the patriarchal promise of the Messiahship in Judah (Gen 49:10).

[10:14]  ² 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).

[26:22]  ³ sn The Judahites increased from 74,600 to 76,500.
