Ex 16:2-3
2 The whole company of Israel complained against Moses and Aaron there in the wilderness. 3 The Israelites said, "Why didn't GOD let us die in comfort in Egypt where we had lamb stew and all the bread we could eat? You've brought us out into this wilderness to starve us to death, the whole company of Israel!"

After all the miracles in Egypt, they were released from slavery, they crossed the Red Sea on dry land and the Egyptians drowned they complained?
