14 Heb “and it will be on the sixth day.”
15 There is a question here concerning the legislation—the people were not told why to gather twice as much on the sixth day. In other words, this instruction seems to presume that they knew about the Sabbath law. That law will be included in this chapter in a number of ways, suggesting to some scholars that this chapter is out of chronological order, placed here for a purpose. Some argue that the manna episode comes after the revelation at Sinai. But it is not necessary to take such a view. God had established the Sabbath in the creation, and if Moses has been expounding the Genesis traditions in his teachings then they would have known about that.
