So they did eat, and were well filled - The word rendered "well" here is intensive. It means that they were abundantly satisfied; that there was no lack; that they had the most ample supply.
For he gave them their own desire - He gave them exactly what they asked. He gave them flesh to eat as they had demanded; and he gave it to them in such quantities that no one could say that he had not enough.

So they did eat, and were well filled,..... Or "exceedingly filled" (m), or too much, as some versions render it; they eat to excess, not merely to satisfy nature, but to gratify their sensual appetite: gluttony is a sin; it is an abuse of the creatures; it hurts the body by filling it with gross humours, and bringing diseases on it; it is injurious to the mind; the heart may be overcharged by it; it disposes it to sin; it leads to impiety, to atheism, and disbelief of a future state, which often go along with it, and ends in destruction, which is the case of those whose god is their belly:
for he gave them their own desire; or their lust (n), what they lusted after, flesh; and they had as much of it as they would, though this was given in judgment; and a sad thing it is when God gives men a fulness of this world's things, and leaves them to the abuse of them, or sends leanness into their souls, and gives them up to their own hearts' lusts.
