3:11-15 Formerly Moses thought himself able to deliver Israel, and set himself to the work too hastily. Now, when the fittest person on earth for it, he knows his own weakness. This was the effect of more knowledge of God and of himself. Formerly, self-confidence mingled with strong faith and great zeal, now sinful distrust of God crept in under the garb of humility; so defective are the strongest graces and the best duties of the most eminent saints. But all objections are answered in, Certainly I will be with thee. That is enough. Two names God would now be known by. A name that denotes what he is in himself, I AM THAT I AM. This explains his name Jehovah, and signifies, 1. That he is self-existent: he has his being of himself. 2. That he is eternal and unchangeable, and always the same, yesterday, to-day, and for ever. 3. That he is incomprehensible; we cannot by searching find him out: this name checks all bold and curious inquiries concerning God. 4. That he is faithful and true to all his promises, unchangeable in his word as well as in his nature; let Israel know this, I AM hath sent me unto you. I am, and there is none else besides me. All else have their being from God, and are wholly dependent upon him. Also, here is a name that denotes what God is to his people. The Lord God of your fathers sent me unto you. Moses must revive among them the religion of their fathers, which was almost lost; and then they might expect the speedy performance of the promises made unto their fathers.

10-22. 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 [Ex 3:11, 13; 4:1, 10] all of which were successfully met and removed—and the happy issue of his labors was minutely described.
