Chasidut for Yoma 154:17
אמר ר' פנחס משום רב הונא צפוראה מעין היוצא מבית קדשי הקדשים בתחילה דומה לקרני חגבים כיון שהגיע לפתח היכל נעשה כחוט של שתי כיון שהגיע לאולם נעשה כחוט של ערב כיון שהגיע אל פתח עזרה נעשה כפי פך קטן והיינו דתנן ראב"י אומר מים
R'Joseph demurred: But, even on a weekday is such action permitted?<span class="x" onmousemove="('comment',' To walk through water up to one's neck.');"><sup>16</sup></span> Does not Scripture say: He measured a thousand cubits and he caused me to pass through the waters, waters that were to the ankles;<span class="x" onmousemove="('comment',' Ezek. XLVII, 3.');"><sup>17</sup></span> hence we infer that it is permitted to pass through water up to the ankles. Again he measured a thousand, and caused me to pass through the waters, waters that were up to the knees;<span class="x" onmousemove="('comment',' Ibid. 4.');"><sup>18</sup></span> hence we learn that it is permitted to pass through waters up to the knees. Again he measured a thousand, and caused me to pass through waters that were to the loins;<span class="x" onmousemove="('comment',' Ibid. 4.');"><sup>18</sup></span> hence we know that it is permissible to pass through water up to the loins. Henceforth: Afterward he measured a thousand, and it was a river that I would not pass through.<span class="x" onmousemove="('comment',' Ibid. v. 5.');"><sup>19</sup></span> Abaye said: It is different with a river whose waters run rapidly.<span class="x" onmousemove="('comment',' As with the river, coming from the Holy of Holies; but this is no precedent.');"><sup>20</sup></span> One might have assumed that it is permissible to swim across such a river, therefore the text reads: For the waters were risen, waters to swim in.<span class="x" onmousemove="('comment',' Ibid. v. 5.');"><sup>19</sup></span> What does 'sahu' mean? - 'Swim', for a swimmer is called 'sayaha'. One might have assumed that it is permissible to pass through such [river] in a small Liburnian boat, therefore the text reads: Wherein, shall go no galley with oars.<span class="x" onmousemove="('comment',' Isa. XXXIII, 21.');"><sup>21</sup></span> One might have assumed that one may cross it in a big Liburnian ship, therefore Scripture says: Neither shall gallant ship pass thereby.<span class="x" onmousemove="('comment',' As with the river, coming from the Holy of Holies; but this is no precedent.');"><sup>20</sup></span> How does that follow from the text? - As R'Joseph interprets it: No fisher's boat goes thereon, no big boat traverses it.<span class="x" onmousemove="('comment',' V. Targum on Prophets a.l.');"><sup>22</sup></span> R'Judah B'Pazzi said: Even the Angel of Death has no permission to cross it, for here it is said: 'Wherein shall go no galley with oars [shayit].'<span class="x" onmousemove="('comment',' Job I, 7. The argument is based on the analogy of expression. The conditions attaching to the 'shayit' in Isaiah inferred from Ezekiel apply also to shut in Job. Hence, just as there it is forbidden, by inference, to cross the river, so may the Angel of Death, as another shayit not do so either.');"><sup>23</sup></span> and there it reads: From going [shut] to and fro in the earth.<span class="x" onmousemove="('comment',' Job I, 7.

Our author proceeds to analyze each word in the Talmud’s parable. He states further that in his sleep, the tzaddik triggers the dispensation of G’d’s largesse, as during his sleep, when his soul is in the celestial regions, he conveys thoughts in those regions that he had been entertaining in his waking hours. His Creator is especially receptive to his wishes while his soul is close to Him during his sleep. According to the Sefer Yetzirah, chapter 4, the letters of the Hebrew alphabet are also known as אבנים, “stones,” the author describing them as being used to build the physical universe and engraving themselves on respective parts of it. In light of the description in the Sefer Yetzirah, it is easy for us to understand that when Yaakov lay down after having taken from “the stones of G’d,” i.e. the letters G’d had used in creating His universe, that he prepared during his sleep to beseech G’d to dispense of His largesse to His creatures on earth.
