(Devarim, Ibid.) "for you shall not cross this Jordan." An analogy: A king decreed that his son not enter his bedchamber — whereupon he entered the palace entrance talking with him; he entered his reception room talking with him. When he came to enter his chamber, he said to him: "From here on, you are forbidden." Likewise, Moses said to the L-rd: "All of me is separated from Eretz Yisrael only by a fifty-ell string-length of this Jordan" — whereupon He said: "and see with your eyes, for you will not cross this Jordan."
