Adam Clarke, on 2Cor 11:31

“The God and Father of our Lord Jesus Christ, who is blessed for ever, knoweth that I lie not.”

“The God and Father of our Lord - Here is a very solemn asseveration; an appeal to the ever blessed God for the truth of what he asserts. It is something similar to his asseveration or oath in Co2 11:10 of this chapter; see also Rom 9:5, and Gal 1:20. And from these and several other places we learn that the apostle thought it right thus to confirm his assertions on these particular occasions. But here is nothing to countenance profane swearing, or taking the name of God in vain, as many do in exclamations, when surprised, or on hearing something unexpected, etc.; and as others do who, conscious of their own falsity, endeavor to gain credit by appeals to God for the truth of what they say. St. Paul's appeal to God is in the same spirit as his most earnest prayer. This solemn appeal the apostle makes in reference to what he mentions in the following verses. This was a fact not yet generally known.”
