And Moses returned. This return unto the Lord is here used in a bad sense for forsaking his office; for Moses is not related to have either calmly prayed, or, as in a difficult emergency, to have humbly sought counsel of the Lord; but, leaving the men with whom he had to do, to have gone back in disgust to God, to demand his dismissal. He returned, then, to God, that the whole undertaking might be abandoned, as though he had never been sent. This is what the words convey, since he openly expostulates with God, because He had permitted His people to be more cruelly entreated, though He had promised them deliverance. At first sight, his madness would seem to be greater than that of the whole people, because he directly and openly accuses God as the author of all the evil which Pharaoh had inflicted; yet I doubt not but that he rather sorrowfully recounted the complaints of the people than spoke his own sentiments. Still his bitterness is not altogether excusable, when he repents of his vocation, and is indignant, because an unsuccessful charge had been intrusted to him. But when he accuses the slackness of God in redeeming His people, it is made apparent how deep is the darkness which had taken possession of his mind. He had been forewarned in good time of the hardness of Pharaoh's heart; he had heard that he would not yield until crushed by God's mighty hand; now, forgetting of all, he marvels that their redemption is not complete. The same thing often occurs to us, that the doctrine of faith and hope, which in peaceful times shines brightly in our hearts and echoes from our tongue, is altogether lost when we come to serious conflict. Wherefore we ought to devote ourselves with greater goodwill to its study, that even in the most trying circumstances the recollection of it may be our support.

And Moses returned unto the Lord - This may imply, either that there was a particular place into which Moses ordinarily went to commune with Jehovah; or it may mean that kind of turning of heart and affection to God, which every pious mind feels itself disposed to practice in any time or place. The old adage will apply here: "A praying heart never lacks a praying place." Lord, wherefore hast thou so evil entreated this people? - It is certain that in this address Moses uses great plainness of speech. Whether the offspring of a testy impatience and undue familiarity, or of strong faith which gave him more than ordinary access to the throne of his gracious Sovereign, it would be difficult to say. The latter appears to be the most probable, as we do not find, from the succeeding chapter, that God was displeased with his freedom; we may therefore suppose that it was kept within due bounds, and that the principles and motives were all pure and good. However, it should be noted, that such freedom of speech with the Most High should never be used but on very special occasions, and then only by his extraordinary messengers.

And Moses returned unto the Lord,.... Bishop Patrick thinks, that this not only intimates that the Lord had appeared to Moses since he came into Egypt, but that there was some settled place where he appeared, and where he might resort to him on all occasions, and therefore is said to return to him; though it may signify no more, than that, instead of staying to give an answer to the officers, which he might be at a loss to do, he went to God, to the throne of grace, by prayer, as he was wont to do in cases of difficulty:
and said, Lord, wherefore hast thou so evil entreated this people? or afflicted them, and suffered them to be thus afflicted; which to ascribe to God was right, whatever were the means or instruments; for all afflictions are of him, and who has always wise reasons for what he does, as he now had; to try the faith and patience of his people; to make the Egyptians more odious to them, and so take them off from following their manners, customs, rites, and superstitions, and make them more desirous of departing from thence to the land of Canaan, nor seek a return to Egypt again; and that his vengeance on the Egyptians for such cruelty and inhumanity might appear the more just, and his power might be seen in the plagues he inflicted on them, and in the deliverance of his people when reduced to the utmost extremity:
why is it that thou hast sent me? he seems to wish he had never been sent, and could be glad to be recalled, something of the same disposition still remaining in him as when first called; since no end was answered by his mission, no deliverance wrought, yea, the people were more afflicted and oppressed than before; and therefore he was at a loss how to account for it that he should be sent at all, seeing nothing came of it to the good of the people.

He expostulated with him. He knew not how to reconcile the providence with the promise, and the commission he had received. Is this God's coming down to deliver Israel? Must I who hoped to be a blessing to them become a scourge to them? By this attempt to get them out of the pit, they are but sunk the farther into it. Wherefore hast thou so evil entreated this people - Even when God is coming towards his people in ways of mercy, yet sometimes he takes such methods that they may think themselves but ill - treated: when they think so, they should go to God by prayer, and that is the way to have better treatment in God's good time. Why is it that thou hast sent me - Pharaoh has done evil to this people, and not one step seems to be taken towards their deliverance. It cannot but sit very heavy upon the spirits of those whom God employs for him, to see that their labour doth no good, and much more to see that it doth hurt, eventually, though not designedly.
