Комментарий к Бамидбар 33:10

ויחנו על ים סוף, ”they encamped near the sea of reeds between Eylim and the desert of Tzin which stretched from the sea of reeds towards the desert that they had come from. This encampment as well as the ones at Dofkah and Elosh, have not been mentioned in the portion of Beshalach but were lumped together in Exodus 16,1 where the Torah wrote: “the whole community of Israel arrived at the desert of Sin.”

ויחנו ברפידים, the reader is referred to Exodus 17,1 for the author’s commentary.
