God, having spoken to Moses, allows him also a liberty of speech, which he here improves; and,

I.He objects his own insufficiency for the service he was called to (Exo 3:11): Who am I? He thinks himself unworthy of the honour, and not par negotio - equal to the task. He thinks he wants courage, and therefore cannot go to Pharaoh, to make a demand which might cost the demandant his head: he thinks he wants skill, and therefore cannot bring forth the children of Israel out of Egypt; they are unarmed, undisciplined, quite dispirited, utterly unable to help themselves; it is morally impossible to bring them out. 1. Moses was incomparably the fittest of any man living for this work, eminent for learning, wisdom, experience, valour, faith, holiness; and yet he says, Who am I? Note, The more fit any person is for service commonly the less opinion he has of himself: see Jdg 9:8, etc. 2. The difficulties of the work were indeed very great, enough to startle the courage and stagger the faith of Moses himself. Note, Even wise and faithful instruments may be much discouraged at the difficulties that lie in the way of the church's salvation. 3. Moses had formerly been very courageous when he slew the Egyptian, but now his heart failed him; for good men are not always alike bold and zealous. 4. Yet Moses is the man that does it at last; for God gives grace to the lowly. Modest beginnings are very good presages.

II.God answers this objection, Exo 3:12. 1. He promises him his presence: Certainly I will be with thee, and that is enough. Note, Those that are weak in themselves may yet do wonders, being strong in the Lord and in the power of his might; and those that are most diffident of themselves may be most confident in God. God's presence puts an honour upon the worthless, wisdom and strength into the weak and foolish, makes the greatest difficulties dwindle to nothing, and is enough to answer all objections. 2. He assures him of success, and that the Israelites should serve God upon this mountain. Note, (1.) Those deliverances are most valuable which open to us a door of liberty to serve God. (2.) If God gives us opportunity and a heart to serve him, it is a happy and encouraging earnest of further favours designed us.

III.He begs instructions for the executing of his commission, and has them, thoroughly to furnish him. He desires to know by what name God would at this time make himself known, Exo 3:13.

1.He supposes the children of Israel would ask him, What is his name? This they would ask either, (1.) To perplex Moses: he foresaw difficulty, not only in dealing with Pharaoh, to make him willing to part with them, but in dealing with them, to make them willing to remove. They would be scrupulous and apt to cavil, would bid him produce his commission, and probably this would be the trial: "Does he know the name of God? Has he the watch-word?" Once he was asked, Who made thee a judge? Then he had not his answer ready, and he would not be nonplussed so again, but would be able to tell in whose name he came. Or, (2.) For their own information. It is to be feared that they had grown very ignorant in Egypt, by reason of their hard bondage, want of teachers, and loss of the sabbath, so that they needed to be told the first principles of the oracles of God. Or this question, What is his name? amounted to an enquiry into the nature of the dispensation they were now to expect: "How will God in it be known to us, and what may we depend upon from him?"

2.He desires instructions what answer to give them: "What shall I say to them? What name shall I vouch to them for the proof of my authority? I must have something great and extraordinary to say to them; what must it be? If I must go, let me have full instructions, that I may not run in vain." Note, (1.) It highly concerns those who speak to people in the name of God to be well prepared beforehand. (2.) Those who would know what to say must go to God, to the word of his grace and to the throne of his grace, for instructions, Eze 2:7; Eze 3:4, Eze 3:10, Eze 3:17. (3.) Whenever we have any thing to do with God, it is desirable to know, and our duty to consider, what is his name.

IV.God readily gives him full instructions in this matter. Two names God would now be known by: -

1.A name that denotes what he is in himself (Exo 3:14): I am that I am. This explains his name Jehovah, and signifies, (1.) That he is self-existent; he has his being of himself, and has no dependence upon any other: the greatest and best man in the world must say, By the grace of God I am what I am; but God says absolutely - and it is more than any creature, man or angel, can say - I am that I am. Being self-existent, he cannot but be self-sufficient, and therefore all-sufficient, and the inexhaustible fountain of being and bliss. (2.) That he is eternal and unchangeable, and always the same, yesterday, today, and for ever; he will be what he will be and what he is; see Rev 1:8. (3.) That we cannot by searching find him out. This is such a name as checks all bold and curious enquiries concerning God, and in effect says, Ask not after my name, seeing it is secret, Jdg 13:18; Pro 30:4. Do we ask what is God? Let it suffice us to know that he is what he is, what he ever was, and ever will be. How little a portion is heard of him! Job 26:14. (4.) That he is faithful and true to all his promises, unchangeable in his word as well as in his nature, and not a man that he should lie. Let Israel know this, I AM hath sent me unto you.

2.A name that denotes what he is to his people. Lest that name I AM should amuse and puzzle them, he is further directed to make use of another name of God more familiar and intelligible: The Lord God of your fathers hath sent me unto you (Exo 3:15): Thus God had made himself know to him (Exo 3:6), and thus he must make him known to them, (1.) That he might revive among them the religion of their fathers, which, it is to be feared, was much decayed and almost lost. This was necessary to prepare them for deliverance, Psa 80:19. (2.) That he might raise their expectations of the speedy performance of the promises made unto their fathers. Abraham, Isaac, and Jacob, are particularly named, because with Abraham the covenant was first made, and with Isaac and Jacob often expressly renewed; and these three were distinguished from their brethren, and chosen to be the trustees of the covenant, when their brethren were rejected. God will have this to be his name for ever, and it has been, is, and will be, his name, by which his worshippers know him, and distinguish him from all false gods; see Kg1 18:36. Note, God's covenant-relation to his people is what he will be ever mindful of, what he glories in, and what he will have us never forget, but give him the glory of: if he will have this to be his memorial unto all generations, we have all the reason in the world to make it so with us, for it is a precious memorial.

Who am I - that I should bring - He was so satisfied that this was beyond his power, and all the means that he possessed, that he is astonished that even God himself should appoint him to this work! Such indeed was the bondage of the children of Israel, and the power of the people by whom they were enslaved, that had not their deliverance come through supernatural means, their escape had been utterly impossible.

And Moses said unto God, who am I, that I should go unto Pharaoh,.... A private person, an exile in a foreign country, a poor shepherd, unknown to Pharaoh, and had no interest in him; and he a great king, and possessed of numerous forces to defend his country, and prevent the Israelites' departure out of it: time was when he was known to a Pharaoh, dwelt in his court, and made a figure there, and had great interest and authority there, being the adopted son of the king's daughter; but now it was otherwise with him:

and that I should bring forth the children of Israel out of Egypt: who though a people numerous, yet unarmed, and held in great bondage; and he might remember how he had been repulsed and rejected by some of them forty years ago, which might be discouraging to him.

Come now therefore, and I will send thee--Considering the patriotic views that had formerly animated the breast of Moses, we might have anticipated that no mission could have been more welcome to his heart than to be employed in the national emancipation of Israel. But he evinced great reluctance to it and stated a variety of objections [Exo 3:11, Exo 3:13; Exo 4:1, Exo 4:10] all of which were successfully met and removed--and the happy issue of his labors was minutely described.
