I guess I’ll fill in again.
The following is from R’ Moshe Sternbuch from his sefer Ta’am Vada’as:
??? ?????? ????? ??????? ?????. When Moshe is davening for the Yidden to be spared, he asks Hashem to remember our z’chus avos.
There is an interesting Rashi on this p’suk. Rashi says that if the Yidden are deserving of the punishment of sreifa (burning) remember Avraham who went into the Kivshon HaAish. If the Yidden are deserving of the punishment of Hereg, remember Yitzchak who went onto the Akeda. And if galus is the punishment, remember Yaakov who needed to flee to the house of Lavan.
R’ Sternbuch says it is interesting that among all the things the Avos did, this is what Moshe chose to mention as the z’chusim to Hashem. Moshe only chose to mention the mesiras nefesh the avos went through as well as the yissurin (difficulties) for the sake of Hashem.
Moshe chose to mention these aspect of their avoda since this is truly the optimum way to serve Hashem. ??????????? ??? ?’ ???????? ?????? ???????? ??????? ????????? ??????? ???????: This is personified by the avoda of our avos in their avodas Hashem
