ויפגע במקום. לשון תפלה וזו תפלת ערבית טרם בא השמש שהרי כתיב ויפגע במקום והדר כי בא השמש אמנם לפי השטה דברכות משמע דזמן ק"ש דערבית לא הוי עד צאת הכוכבים: ויפגע במקום, “he prepared to pray intensely at a certain location (known to him as a suitable location for prayer);” according to our author, these words mean that he prepared to offer a prayer, and that we find this expression for preparing to pray also in Jeremiah 7,16: i.e. ואל תפגע בי, “and do not pray to Me (on behalf of your people)” According to the Talmud tractate B’rachot, folio 26, Yaakov “invented” the daily evening prayer preparing himself shortly before sunset before doing so. The recital of the k’riyat shma is to await the visibility of three stars in the sky before it may be recited.
