Midrash su Geremia 49:7

When R. Joshua b. Chanania was dying, the Rabbis asked him: "What will be our relations with the infidels? Who will discuss with them?" He rejoined (Jer. 49, 7) Is counsel vanished from the sons, is their wisdom become corrupt? "This is to mean that when the children of God love their adviser, the wisdom of their adversaries becomes corrupt." And if we wish, we may infer the same conclusion from the following passage (Gen. 33, 12) Let us depart and move farther, and I will travel near thee" [which means that we will be always equal to our opponent]. While ascending the steps of the house of Rabba b. Shila, R. Hla heard a child read the following passage (Amos 4, 13) He that formeth the mountains, and createth the wind and declareth unto man what is his thought? And he said: "If there is a slave whose master can declare to him what his secret thought is, what hope can there be for him?" What is the meaning of, He declareth? Said Rab: "Even a trivial conversation between a man and his own wife is mentioned to him at the time of his death."
