Gevurot Meyruach Hakodesh 27:33-37

Just before boker, Rav Sha'ul was urging everyone to take okhel (food), saying, Today is the 14 th day you have been held in suspense and are continuing without eating, having taken nothing. Therefore, I encourage you to take okhel, for it is for your deliverance, for none of you will lose a hair from your heads. And having said these things, and having taken lechem, Rav Sha'ul said the HaMotzi before all, and, after the Betzi'at HaLechem, he began to eat. And receiving ometz lev, they all took okhel. Now there were in all two hundred and seventy-six nefashot in the oniyah.
