Numbers 13:5

And the LORD spake unto Moses, saying,

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.

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.

And these were their names: of the tribe of Reuben, Shammua the son of Zaccur.
