The rabbke with them began to crave other food

Numbers 11:1-15
Now the people complained about their hardships in the hearing of the Lord, and when he heard them his anger was aroused. Then fire from the Lord burned among them and consumed some of the outskirts of the camp. 
The rabble(烏合之眾) with them began to crave other food, and again the Israelites started wailing and said, “If only we had meat to eat! 5 We remember the fish we ate in Egypt at no cost—also the cucumbers, melons, leeks, onions and garlic. But now we have lost our appetite; we never see anything but this manna!” 
Moses heard the people of every family wailing at the entrance to their tents. The Lord became exceedingly angry, and Moses was troubled.
Mose asked the Lord, ...What have I done to displease you that you put the burden of all these people on me?...Where can I get meat for all these people? They keep wailing to me, ‘Give us meat to eat!’  I cannot carry all these people by myself; the burden is too heavy for me.
The first delicious taste of manna was like wafers made with honey. Now sheer monotony(單調) makes it stick in the gullet(食道) like sawdust. Mouth-watering thoughts of all the fish and vegetables that abounded in the Nile delta soon produce an irresistible craving: 'If only...' God gives them what they want, till they are sick of it.
Why?
Man's desire are unlimited,
People complained about their hardship in the hearing of the Lord, and wailing about food.
Moses as a leader of these people he felt tired and trouble to this burden, it is too heavy to carry so huge people in desert.
Manna is nice food given from heaven, it is delicious, but any food eat longer time, people feel monotony makes it stick in the gullet.
Only focus on the Lord with thanks and remember what God has given us much grace, for God does not forsake us,
How?
Do not forget what God has loved me and gave me so much mercy and grace on me. No one can compare with the Lord in my life.
