Please read the passage before reading the comments.
Be careful how we complain to God. God may answer our complaints in some roundabout way. The Israelites complained about not having meat and bread. God sent them quail, but they had to catch them. God gave them manna in the desert, but they had to pick it up only on weekdays and only in a certain amount.
Quail is a migratory bird. It follows the wind, but if the wind shifts, the quail may have to land to refuel themselves and regain their strength. If so, they are easy to catch. Out of the clear blue sky, with the change in wind, God dropped quail into the arms of the hungry people. The dew of night yielded something to eat in the morning. Its presence in the land caused the Israelites to Ask what it was. Then they called it “what it was”, or manna.
Sometimes God saves us in ways that seem strange to us. Sometimes we get manna presented to us as God’s surprise way of answering our prayer. Maybe this means that we had better be perfectly clear what we treasure and are asking God for in prayer. A prayer for deliverance may be answered by removing us from a situation or by introducing someone else into the situation or by other way.
The Israelites complained about not having food to eat. They may have wanted T-bone steak, but they got quail and manna instead. We may want our needs taken care of according to our plan A. but God may use God’s plan A instead.
