The provisions of Israel, brought from Egypt, were spent by the middle of the second month, and they murmured. It is no new thing for the greatest kindness to be basely represented as the greatest injuries.
They so far undervalue their deliverance, that they wished they had died in Egypt; and by the hand of the Lord, that is, by the plagues which cut off the Egyptians. We cannot suppose they had plenty in Egypt, nor could they fear dying for want in the wilderness, while they had flocks and herds: none talk more absurdly than murmurers.
When we begin to fret, we ought to consider, that God hears all our murmurings. God promises a speedy and constant supply. He tried whether they would trust him, and rest satisfied with the bread of the day in its day.
Thus he tried if they would serve him, and it appeared how ungrateful they were. When God plagued the Egyptians, it was to make them know he was their Lord; when he provided for the Israelites, it was to make them know he was their God.
