Charles H. Spurgeon on Psalms 104:27

These wait all upon thee. They come around thee as fowls around the farmer's door at the time for feeding, and look up with expectation. Men or marmots, eagles or emmets, whales or minnows, they alike rely upon thy care. That thou mayest give them meat in due season; that is to say, when they need it and when it is ready for them. God has a time for all things, and does not feed his creatures by fits and starts; he gives them daily bread, and a quantity proportioned to their needs. This is all that any of us should expect; if even the brute creatures are content with a sufficiency we ought not to be more greedy than they.
