Numbers 11:6

6.But now our soul is dried away. They complain that they are almost wasted away with famine and hunger, whilst they are abundantly supplied with manna; in the same way as they had just been loudly declaring that they had lived in Egypt for a very little money; as if they were affected by a great dearth of provisions, when, by the pure liberality of God, a kind of food was provided for them, more easy to prepare than any other, and so actually prepared without trouble or cost. But such is the malignity and ingratitude of men, that they count all God’s bounty for nothing, whilst they are brooding over their own importunate lusts. Many in their gluttony consume, and bring to naught whatever God bestows upon them: others, in their avarice, dry up the fountain of His liberality, which else would be inexhaustible. But these, in the midst of their abundance, say that they are dry, because insatiable cupidity inflames them, so that God’s blessing, however ample, cannot satisfy them. Thus the rain, washing the hard rock, wets it not within, neither tempers its dryness by its moisture. Since, therefore, a contempt of God’s blessings withers them all, like a hot blast, let us learn to assign them their due honor, that they may be supplied to us in sufficiency. Thus will be fulfilled in our ease:

“The righteous shall flourish like the palm-tree: he shall grow like a cedar in Lebanon. Those that be planted in the house of the Lord shall flourish in the courts of our God. They shall still bring forth fruit in old age; they shall be fat and flourishing.”
(Psalms 92:12.)

For Scripture does not so often declare in vain that God satisfies the longing souls, and filleth the hungry with food. They complain that there is nothing before their eyes but manna: as if their loathing of this one excellent and abundant kind of food was actual famine.
