R. Yossi Haglili says: The speaking was on Rosh Chodesh, the taking on the tenth, and the slaughtering on the fourteenth. You say this, but perhaps the speaking was on the tenth, and the slaughtering and the taking on the fourteenth? If is, therefore, written (Ibid. 6) "And it shall be to you for a keeping until the fourteenth." If you say this (i.e., that he may slaughter it on the tenth), you have uprooted the entire verse (from its meaning)! You must revert, then, to the first formulation.
