Psalms 106:15

Those that will not wait for God's counsel, shall justly be given up to their own hearts' lusts, to walk in their own counsels. An undue desire, even for lawful things, becomes sinful. God showed his displeasure for this. He filled them with uneasiness of mind, terror of conscience, and self-reproach. Many that fare deliciously every day, and whose bodies are healthful, have leanness in their souls: no love to God, no thankfulness, no appetite for the Bread of life, and then the soul must be lean. Those wretchedly forget themselves, that feast their bodies and starve their souls. Even the true believer will see abundant cause to say, It is of the Lord's mercies that I am not consumed. Often have we set up idols in our hearts, cleaved to some forbidden object; so that if a greater than Moses had not stood to turn away the anger of the Lord, we should have been destroyed. If God dealt severely with Moses for unadvised words, what do those deserve who speak many proud and wicked words? It is just in God to remove those relations that are blessings to us, when we are peevish and provoking to them, and grieve their spirits.

And he gave them their request. Prayer may be answered in anger and denied in love. That God gives a man his desire is no proof that he is the object of divine favour, everything depends upon what that desire is. But sent leanness into their soul. Ah, that "but!" It embittered all. The meat was poison to them when it came without a blessing; whatever it might do in fattening the body, it was poor stuff when it made the soul lean. If we must know scantiness, may God grant it may not be scantiness of soul: yet this is a common attendant upon worldly prosperity. When wealth grows with many a man his worldly estate is fatter, but his soul's state is leaner. To gain silver and lose gold is a poor increase; but to win for the body and lose for the soul is far worse. How earnestly might Israel have unprayed her prayers had she known what would come with their answer! The prayers of lust will have to be wept over. We fret and fume till we have our desire, and then we have to fret still note because the attainment of it ends in bitter disappointment.
