Here is the people's sin; they complained. See the sinfulness of sin, which takes occasion from the commandment to be provoking. The weakness of the law discovered sin, but could not destroy it; checked, but could not conquer it.
They complained. Those who are of a discontented spirit, will always find something to quarrel or fret about, though the circumstances of their outward condition be ever so favourable. The Lord heard it, though Moses did not.
God knows the secret frettings and murmurings of the heart, though concealed from men. What he noticed, he was much displeased with, and he chastised them for this sin. The fire of their wrath against God burned in their minds; justly did the fire of God's wrath fasten on their bodies; but God's judgments came on them gradually, that they might take warning.
It appeared that God delights not in punishing; when he begins, he is soon prevailed with to let it fall.
