Whose missing and why?

[Esther]

Can you tell me which tribe is missing and why?

I was surprised to find this out.


Num 13:1 And the LORD spake unto Moses, saying,
:2 Send thou men, that they may search the land of Canaan, which I give unto the children of Israel: of every tribe of their fathers shall ye send a man, every one a ruler among them.
:3 And Moses by the commandment of the LORD sent them from the wilderness of Paran: all those men were heads of the children of Israel.
:4 And these were their names: of the tribe of Reuben, Shammua the son of Zaccur.
:5 Of the tribe of Simeon, Shaphat the son of Hori.
:6 Of the tribe of Judah, Caleb the son of Jephunneh.
