a Bible passage
20. Now the things which I write to you. This affirmation extends to the whole narrative. The vast earnestness of Paul on this subject is evinced by his resorting to an oath, which cannot lawfully be employed but on great and weighty occasions. Nor is it wonderful that he insists with so much earnestness on this point; for we have already seen to what expedients the impostors had recourse in order to take from him the name and credit of an apostle. Now the modes of swearing used by good men deserve our attention; for we learn from them that an oath must be viewed simply as an appeal to the judgment-seat of God for the integrity and truth of our words and actions; and such a transaction ought to be guided by religion and the fear of God.
