The people complain to Moshe and Aharon that they ate better food in Egypt. Hashem sends quails so they can have meat and provides them with manna. It is a miraculous bread that falls from the sky every day except Shabbos. On Friday a double portion descends to supply the Shabbos needs. Nobody is able to obtain more than a daily portion, but manna collected on Friday suffices for two days so the Jews can rest on Shabbos.
Some manna is set aside as a memorial for future generations.
After the Jews complain again about the lack of water, Moshe miraculously produces water from a rock. Amalek then attacks the Jews. Joshua leads the Jews in battle while Moshe prays for their welfare. It took her forever. There's a piece of red sticking out here.
