“And Moses assembled all the community of Israelites and said to them…” Countless times Moses assembled the people, so why stress it this time? The Ohr HaHayim explains that at the end of last parasha Moses’ face became “terrifyingly luminous” and the people became afraid to draw near him. To counter their fear, Moses gathered them together lest they stop visiting him and so the verse stresses that he gathered all the community – for he wanted everyone to see that they had nothing to fear and he would remain accessible to them.
