Therefore hath he mercy, &c.— "Therefore, that his name and power may be made known, and taken notice of in all the earth, he is kind and bountiful to one nation, and suffers another to go on obstinately in their opposition to him; that his taking them off by some signal calamity, and the ruin brought on them by the visible hand of his providence, may be seen and acknowledged to be an effect of their standing out against him; as in the case of Pharaoh. For this end, he is bountiful to whom he will be bountiful, and whom he will he permits to make such an use of his forbearance towards them, as to persist obdurately in their provocation of him, and draw on themselves exemplary destruction." See Locke, Whitby, and particularly the note on Exodus 9:34-35.
