Numbers 13:1-3

And Jehovah spake unto Moses, saying, Send thou men, that they may spy out 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 prince among them. And Moses sent them from the wilderness of Paran according to the commandment of Jehovah: all of them men who were heads of the children of Israel.
