John Calvin's Bible Commentary
Genesis 47:22
22.Only the land of the priests. The priests were exempted from the common law, because the king granted them a maintenance. It is, indeed, doubtful, whether this was a supply for their present necessity, or whether he was accustomed to nourish them at his own expense. But seeing that Moses makes mention of their lands, I rattler incline to the conjecture, that, whereas they had before been rich, and this dearth had deprived them of their income, the king conferred this privilege upon them; and hence it arose that their lands remained unto them free. (187) The ancient historians, however, injudiciously invent many fables concerning the state of that land. I know not whether the statement that the farmers, content with small wages, sow and reap for the king and the priests, is to be traced to this regulation of Joseph or not. But, passing by these things, it is more to the purpose to observe, what Moses wished distinctly to testify; namely, that a heathen king paid particular attention to Divine worship, in supporting the priests gratuitously, for the purpose of sparing their lands and their property. Truly this is placed before our eyes, as a mirror, in which we may discern that a sentiment of piety which they cannot wholly efface, is implanted in the minds of men. It was the part of foolish, as well as of wicked superstition, that Pharaoh nourished such priests as these, who infatuated the people by their impostures: yet this was, in itself, a design worthy of commendation, that he did not suffer the worship of God to fall into decay; which, in a short time, must have happened, if the priests had perished in the famine. Whence we infer how sedulously we ought to be on our guard, that we undertake nothing with an indiscreet zeal; because nothing is more easy, in so great a corruption of human nature, than for religion to degenerate into frivolous trifles. Nevertheless, because this inconsiderate devotion (as it may be called) flowed from a right principle, what should be the conduct of our princes, who desire to be deemed Christians? If Pharaoh was so solicitous about his priests, that he nourished them to his own destruction, and that of his whole kingdom, in order that he might not be guilty of impiety against false gods; what sacrilege is it, in Christian princes, that the lawful and sincere ministers of holy things should be neglected, whose work they know to be approved by God, and salutary to themselves? But it may be asked, whether it was lawful for holy Joseph to undertake this office, for by so doing, he employed his labor in cherishing impious superstitions? But though I can readily grant that in such great, and arduous, and manifold offices of trust, it was easy for him to slide into various faults; yet I dare not absolutely condemn this act; nor can I, however, deny that he may have erred, in not resisting these superstitions with sufficient boldness. But since he was required by no law, to destroy the priests by hunger, and was not altogether allowed to dispense the king’s corn at his own pleasure; if the king wished that food should be gratuitously supplied to the priests, he was no more at liberty to deny it to them than to the nobles at court. Therefore, though he did not willingly take charge of such dependents, yet when the king imposed the duty upon him, he could not refuse it, though he knew them to be unworthy to be fed on the dirt of oxen.
