This is a kavvanah (intention) distributed beginning in 2017 for Jewish soldiers on active service during Yom Kippur to use before eating or drinking a limited amount of nourishment in order to sustain their attention and readiness. The text of the prayer here is that which was distributed by Rabbi Captain Udi Schwartz, head of the chief rabbi for Tsahal (IDF), and published by Arutz 7. The kavvanah is derived from one published in 1983 by Rav Yitschok Zilberstein for those who, due to their state of health, must eat or drink in order to live (find Toras haYoledes (1983), chapter 52, section 10, p. 357; pp. 331-332 in the bilingual edition 1989). That kavvanah, according to Rabbi Zilberstein was, “הועתק ממחזור עתיק” (“copied from an old maḥzor”).
