Chp. 15 verse 26 - Chp. 16 verse 27: Chp. finishes with their stay at Elim. Chp. 16, from Elim they reach the wilderness of Sin. The people complain about a lack of food. Hashem tells Moshe to tell the people that He will have it rain Mann from heaven everyday except Shabbos when they will receive a double portion. Hashem would give them quail in the evening and mann in the morning. They were instructed not to leave over any mann for the morning and if they did it would turn to worms and maggots and stink, not everyone obeyed. On the sixth day they saw that they had a double portion and Moshe then instucted them about Shabbos. He told that the mann would not fall on Shabbos but some people still went out to collect but none was found.
