Psalms 116:10 - Joseph Benson’s Commentary on the Old and New Testaments

I have believed God's promise of deliverance; therefore have I spoken What I have now said; or, I have firmly believed, and trusted in God's almighty power, and ever watchful providence, and therefore have addressed my prayer unto him with confidence in my greatest dangers and distresses. In this, or a similar sense, this clause is quoted by St. Paul, 2 Corinthians 4:13, with application to himself and his fellow-ministers, who, though they were exposed everywhere to sufferings for Christ's sake, and were even in danger of being put to death wherever they came; yet were neither ashamed nor afraid to own him, because they confided in the promise he had made them of a blessed resurrection.
