John Wesley on 2 Corinthians 1:23

I call God for a record upon my soul - Was not St. Paul now speaking by the Spirit? And can a more solemn oath be conceived? Who then can imagine that Christ ever designed to forbid all swearing? That to spare you I came not yet to Corinth - Lest I should be obliged to use severity. He says elegantly to Corinth, not to you, when be is intimating his power to punish.
