John Wesley on Exodus 16:3

They so undervalue their deliverance, that they wish, they had died in Egypt, nay, and died by the hand of the Lord too. That is, by some of the plagues which cut off the Egyptians; as if it were not the hand of the Lord, but of Moses only, that brought them into this wilderness. 'Tis common for people to say of that pain, or sickness, which they see not second causes of, It is what pleaseth God, as if that were not so likewise which comes by the hand of man, or some visible accident. We cannot suppose they had any great plenty in Egypt, how largely soever they now talk of the flesh - pots, nor could they fear dying for want in the wilderness while they had their flocks and herds with them; but discontent magnifies what is past, and vilifies what is present, without regard to truth or reason. None talk more absurdly than murmurers.
