Numbers 13:25

The Spies Return

²⁴ That place was called the valley of Eshcol, because of the cluster which the sons of Israel cut down from there. ²⁵ When they returned from spying out the land, at the end of forty days, ²⁶ they proceeded to come to Moses and Aaron and to all the congregation of the sons of Israel in the wilderness of Paran, at Kadesh; and they brought back word to them and to all the congregation and showed them the fruit of the land.
