Gill's Exposition of the Entire BibleI will smite them with the pestilence, and disinherit them,....

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. |
