Isaiah 14:14 - Albert Barnes' Notes on the Bible

I will be like the Most High - There is a remarkable resemblance between this language and that used in 2 Thessalonians 2:4, in regard to antichrist: ‘He, as God, sitteth in the temple of God, showing himself that he is God.’ And this similarity is the more remarkable, because antichrist is represented, in Revelation 17:4-5, as seated in babylon - the spiritual seat of arrogance, oppression, and pride. Probably Paul had the passage in Isaiah in his eye when he penned the description of antichrist.
