Charles H. Spurgeon on Psalms 106:14

But lusted exceedingly in the wilderness. Though they would not wait God's will, they are hot to have their own. When the most suitable and pleasant food was found them in abundance, it did not please them long, but they grew dainty and sniffed at angel's food, and must needs have flesh to eat, which was unhealthy diet for that warm climate, and for their easy life. This desire of theirs they dwelt upon till it became a mania with them, and, like a wild horse, carried away its rider. For a meal of meat they were ready to curse their God and renounce the land which floweth with milk and honey. What a wonder that the Lord did not take them at their word! It is plain that they vexed him greatly, And tempted God in the desert. In the place where they were absolutely dependent upon him and were everyday fed by his direct provision, they had the presumption to provoke their God. They would have him change the plans of his wisdom, supply their sensual appetites, and work miracles to meet their wicked unbelief: these things the Lord would not do, but they went as far as they could in trying to induce him to do so. They failed not in their wicked attempt because of any goodness in themselves, but because God "cannot be tempted, " —temptation has no power over him, he yields not to man's threats or promises.
