Midrash su Numeri 13:20

"Samuel wrote his book," but is it not written And Samuel died? The book was finished by Gad the seer and Nathan the Prophet. "David wrote his book with the help of the ten elders." Why did the Baraitha not enumerate also Ethan the Ezrachite? Rab said: "Ethan the Ezrachite is Abraham, for it is written here (Ps. 89, 1) Ethan the Ezrachite, and it is also written (Is. 41, 2) Who waked up from the East (Mimizrach)," etc. It enumerates Moses, and also Heiman; did not Rab say that Heiman means Moses, for it is written here Heiman and it is written (Num. 12, 7) In all my house is he (Ne'eman) faithful. There were two Heimans. "Moses wrote his book, the chapter of Bilam and Job." This verifies the statement of R. Levy b. Lachma, who said that Job lived in the time of Moses. Raba, however, said: "Job lived in the time of the spies who were sent by Moses to investigate Palestine, for it is written concerning Job (Job 1, 1) Utz, and dealing with the spies, Moses also mentions a word similar to this (Etz, a tree). But how can you say that Utz and Etz are the same? Moses thus said to Israel: "There is a man whose years are as numerous as that of a tree and who protects his generation like a tree protects its branches."

12 (Numb. 13:17) “When Moses sent them […] then he said unto them, ‘Go up here into the Negeb”: Why [first] into the Negeb? Because this is what the merchants do. They show the inferior goods first, and after that they show the best. (Vs. 18) “And you are to see what the land is like”: Three times did Moses tell them, “look over the Land of Israel” (in vss. 18, 19, 20). Why? The first, he said, “See what the land is.” He said to them, “Observe the land. There is land that raises strong men, and there is [land] that raises weaklings. There is also [land] that raises armies,¹⁷Gk.: Ochloi. and there is [land] that diminishes armies.” Thus did he charge them (in Numb. 13:18), “as for the people who dwell in it, are they mighty [or] weak?” (Numb. 13:19) “And what of the land, is it good or bad […]?” And how will you know about their strength? (Numb 13:19 cont.) “Are they in camps or in strongholds”: If they dwell in camps, they are mighty and depend upon their strength; but if they are in strongholds, they are weak and have fearful hearts. (Numb. 13:20) “And what of the land, Is it fertile [or lean]”: [How do we determine] whether its fruits are light or fat. He said to them, “Look at its stones and pebbles. If they are of flint, they are fat; and if they are of clay, they are lean.” (Ibid., cont.) “Now the time was the time for the first-fruits of the grapes”: From here you learn that [the month of] Tammuz is never without figs and grapes.
