Psalms 78:20

The waters gushed out; which, all things consider seems not so wonderful, since fountains of water something break forth unexpectedly from or through rocks. But it is far more difficult to give us bread and flesh, which we know not whether he can do. Or at least we have just cause to doubt of his good will to us, who hath made a a penurious provision for us, and denies us these common blessings of bread and flesh, which he gives to the was of men.
