Reference for Rosh Hashanah 67:18
ולהאי תנא דמייתי לה ממדבר אי מה להלן חצוצרות אף כאן חצוצרות
The words 'Ye shall proclaim' mentioned by the All-Merciful indicate that the shofar should be taken in the hand,<span class="x" onmousemove="('comment',' And not blown. ,rcgvu');"><sup>27</sup></span> and the other, [what says he to this? ] - The lesson of R'Mattenah you can learn from the fact that the text uses an unusual expression,<span class="x" onmousemove="('comment',' The word lit., 'and ye shall cause to pass' instead of 'you shall blow'.');"><sup>28</sup></span> but that the word means 'taking in the hand' you could not maintain, for one can compare the expression 'passing' here with the expression 'passing' used in connection with Moses.<span class="x" onmousemove="('comment',' [This is apparently the meaning of this difficult passage].');"><sup>29</sup></span>
