2 Kings 4:38

We have here Elisha in his place, in his element, among the sons of the prophets, teaching them, and, as a father, providing for them; and happy it was for them that they had one over them who naturally cared for their state, under whom they were well fed and well taught. There was a dearth in the land, for the wickedness of those that dwelt therein, the same that we read of, Kg2 8:1. It continued seven years, just as long again as that in Elijah's time. A famine of bread there was, but not of hearing the word of God, for Elisha had the sons of the prophets sitting before him, to hear his wisdom, who were taught, that they might teach others. Two instances we have here of the care he took about their meat. Christ twice fed those to whom he preached. Elisha was in the more care about it now because of the dearth, that the sons of the prophets might not be ashamed in this evil time, but, even in the days of famine, might be satisfied, Psa 37:19. I. He made hurtful food to become safe and wholesome. 1. On the lecture-day, the sons of the prophets being all to attend, he ordered his servant to provide food for their bodies, while he was breaking to them the bread of life for their souls.

PURIFIES DEADLY POTTAGE. (Kg2 4:38-41) there was a dearth in the land--(see on Kg2 8:1). the sons of the prophets were sitting before him--When receiving instruction, the scholars sat under their masters. This refers to their being domiciled under the same roof (compare Kg2 6:1). Set on the great pot--As it is most likely that the Jewish would resemble the Egyptian "great pot," it is seen by the monumental paintings to have been a large goblet, with two long legs, which stood over the fire on the floor. The seethed pottage consisted of meat cut into small pieces, mixed with rice or meal and vegetables.
