Numbers 13:1-2, 6-8, 16

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.

Of the tribe of Judah, Caleb the son of Jephunneh. Of the tribe of Issachar, Igal the son of Joseph. Of the tribe of Ephraim, Oshea the son of Nun.

These are the names of the men which Moses sent to spy out the land. And Moses called Oshea the son of Nun Jehoshua.
