以利已經非常年老。他聽說了他兒子們對全以色列所做的一切事，又聽說他們與聚集在會幕門口的婦女同寢。

That they would lie. The explanation is according to the simple sense. Our Rabbis however said10In Maseches Yoma 9a-b. that since they delayed [the sacrifice of] their birds11 See Vayikra 15:29 and 22:6-8. and they would wait until they would see their birds being offered, Scripture charges them as though they had lain with them.12See Maseches Shabbos 55b. Metzudas Dovid translates this phrase as “they would cause the women who assembled at the entrance of the Tent of Meeting to sleep there,” thereby not allowing them to return to their homes and husbands.
