This is the first recorded miracle of its kind - a supernatural and inexplicable multiplication of food (compare 2-Kings 4:42-44; Matthew 14:15-21; Matthew 15:32-38). The sacred record does not explain these miracles; but if the explanations sometimes suggested - that there was a transformation of previously existing matter into meal, oil, fish, and bread - be the true one, the marvel of the thing would not be much greater than that astonishing natural chemistry by which, in the growth of plants, particles of water, air, and earth are transmuted into fruits and grains of corn, and so fitted to be human food. There would be a difference in the agency employed and in the time occupied in the transmutation, but the thing done would be almost the same.

The barrel of meal wasted not - She continued to take out of her jar and out of her bottle the quantity of meal and oil requisite for the consumption of her household; and without carefully estimating what was left, she went with confidence each time for a supply, and was never disappointed. This miracle was very like that wrought by Jesus at the marriage at Cana in Galilee: as the servants drew the water out of the pots, they found it turned into wine; and thus they continued to draw wine from the water-pots till the guests had been sufficiently supplied.

And the barrel of meal wasted not, neither did the cruse of oil fail, according to the word of the Lord, which he spake by Elijah. There being a continual increase and supply of both, through the mighty power of God working a continued miracle; just as the loaves and fishes were increased while the disciples were eating, Matthew 14:19.

Wasted not - See how the reward answered the service. She made one cake for the prophet and was repaid with many for herself and her son. What is laid out in charity is set out to the best interest, an upon the best securities.
