[What did The Other see that made him go astray?] Once, he was sitting and studying in the Valley of Gennaser, and he saw a man climb to the top of a palm tree and take the mother bird away from her children, and then come down unharmed. Then, the next day, he saw another man climb up to the top of the palm tree and take the children and send away the mother bird. He came down from the tree, and he was bitten by a snake and died. He said, “It is written (in Deuteronomy 16:7), "You shall send away the mother and take the children, in order that all will be good for you, and your days shall be long.” Where was his good?! Where was his long life?!?
But he didn’t know Rabbi Yaakov’s interpretation! “In order that all will be good for you…” in the world to come, which will be entirely good, “and your days shall be long,” in the messianic age, which will be eternal.
