(12) And will make of thee a greater nation and mightier than they.--A similar promise had been given to Moses on occasion of the rebellion at Sinai, and Moses on that occasion interceded with God on behalf of His people in like manner as at this time (Exodus 32:10-12).

Verse 12. - And will make of thee a greater nation and mightier than they. By electing Moses, in the place of Jacob, to be the founder and ancestor of the chosen race, God would still have made good his promises to Abraham, and would only have vindicated for himself the same freedom of choice which he had used in the case of Ishmael and of Esau. We cannot, however, regard this offer as embodying a deliberate intention, for we know that God did not really mean to cast off Israel; nor can we regard it as expressing the anger of the moment, for it is not of God to be hasty. We must understand it distinctly as intended to try the loyalty and charity of Moses, and to give him an opportunity of rising to the loftiest height of magnanimity, unselfishness, and courage. Moses would unquestionably have been less noble than he was if he had listened to the offer; it is therefore certain that the offer was only made in order that it might be refused (cf. Exodus 32:10).

14:11-19 Moses made humble intercession for Israel. Herein he was a type of Christ, who prayed for those that despitefully used him. The pardon of a nation's sin, is the turning away the nation's punishment; and for that Moses is here so earnest. Moses argued that, consistently with God's character, in his abundant mercies, he could forgive them.I will smite them with the pestilence, and disinherit them,.... Deprive them of inhabiting the land; so as many as died of the pestilence were even all the spies who brought an evil report of the good land, Numbers 14:37; with respect to the body of the people, this is to be considered not as a peremptory decree or a determined point; but is delivered partly by way of proposal to Moses, to draw out from him what he would say to it; and partly by way of threatening to the people, to bring them to a sense of their sin and repentance for it:

and will make of thee a greater nation, and mightier than they: this anticipates an objection that might be made, should the people of Israel be cut off by the plague, and so disinherited of the land of Canaan, what will become of the oath of God made to their fathers? to which the answer is, it would be fulfilled in making the posterity of Moses as great or a greater and more powerful nation than Israel now was, and by introducing them into the land of Canaan, who would be of the seed of the fathers of Israel, as Jarchi observes, as those people were; and this was said to prove Moses, and try his affection to the people of Israel; and give him an opportunity of showing his public and disinterested spirit.
