Numbers 13:1-3, 21-30
The LORD said to Moses, "Send men to spy out the land of Canaan, which I give to the people of Israel; from each tribe of their fathers shall you send a man, every one a leader among them." So Moses sent them from the wilderness of Paran, according to the command of the LORD, all of them men who were heads of the people of Israel.
So they went up and spied out the land from the wilderness of Zin to Rehob, near the entrance of Hamath. They went up into the Negeb, and came to Hebron; and Ahi'man, She'shai, and Talmai, the descendants of Anak, were there. (Hebron was built seven years before Zo'an in Egypt.) And they came to the Valley of Eshcol, and cut down from there a branch with a single cluster of grapes, and they carried it on a pole between two of them; they brought also some pomegranates and figs. That place was called the Valley of Eshcol, because of the cluster which the men of Israel cut down from there. At the end of forty days they returned from spying out the land.
And they came to Moses and Aaron and to all the congregation of the people of Israel in the wilderness of Paran, at Kadesh; they brought back word to them and to all the congregation, and showed them the fruit of the land. And they told him, "We came to the land to which you sent us; it flows with milk and honey, and this is its fruit. Yet the people who dwell in the land are strong, and the cities are fortified and very large; and besides, we saw the descendants of Anak there. The Amal'ekites dwell in the land of the Negeb; the Hittites, the Jeb'usites, and the Amorites dwell in the hill country; and the Canaanites dwell by the sea, and along the Jordan." But Caleb quieted the people before Moses, and said, "Let us go up at once, and occupy it; for we are well able to overcome it."
