Turn from thy fierce wrath — Not as if he thought God were not justly angry, but he begs that he would not be so greatly angry as to consume them. Let mercy rejoice against judgment; repent of this evil — Change the sentence of destruction into that of correction, against thy people which thou broughtest up out of Egypt — For whom thou hast done so great things? Wherefore should the Egyptians say, For mischief did he bring them out — Israel is dear to Moses, as his kindred, as his charge; but it is the glory of God that he is most concerned for. If Israel could perish without any reproach to God's name, Moses could persuade himself to sit down contented; but he cannot bear to hear God reflected on; and therefore this he insists upon, Lord, What will the Egyptians say? They will say, God was either weak, and could not, or fickle, and would not compleat the salvation he begun.
