And they kept the passover— It was the more necessary to repeat the injunction for the observation of the passover, Numbers 9:2 as they might have concluded, from Exodus 12:25 that they were under no obligation to keep it in the wilderness; but, being now in a quiet state, and having rested for almost a whole year, they had that leisure for the observance of it, which, in their future unsettled condition, we do not find they had afterwards; not even circumcising their children, Judges 5:5 who, consequently, could not eat of the passover. Exodus 12:48.
