Deuteronomy 9:29

Yet they are Thy people and Thine inheritance, which Thou broughtest out by Thy mighty power and by Thy stretched out arm. This prayer, if compared with that given Exodus 32:11, shows that Moses here noted down the gist of his intercessory pleading during those memorable forty days, when he varied his petition from time to time, as he struggled with the Lord for the people whom he loved. The true prayer of intercession is importunate, but not willful, and bases its arguments upon the promises of the Lord, appealing to His honor and love.
