John Calvin Commentary Numbers 11:13

"Whence should I have flesh to give unto all this people? for they weep unto me, saying, Give us flesh, that we may eat." — Numbers 11:13 (ASV)

From where should I have flesh to give to all this people? He justly, indeed, accuses the people and denies that he possesses flesh with which to satisfy so great a multitude. But he is wrong in expostulating with God, as if he were burdened beyond his strength; for, since God knew that he was unequal to so many difficulties, He supported him by the influence of His Spirit.

But he sinned most gravely in the conclusion of his complaint, requesting God to kill him. In these words, we see how far even the best of God’s servants may be carried away when they give too great indulgence to their passions. For it is the longing of despair to seek to be removed from the world, so that death may bring our troubles to an end.

Since the impetuosity of his grief hurried away Moses, God’s most chosen servant, to this extreme, what might not happen to us if impatience should gain dominion over our hearts? Let us, then, learn to put a stop to this disease promptly.
