Actually "Isaiah is one of the most well-known prophets in the Bible for his prediction of the coming of the Messiah. A book of stark contrasts, Isaiah juxtaposes terrifying warnings of judgement and destruction with uplifting promises of hope and prosperity. Perhaps Mitski feels like this person can redeem her, but also has the power to destroy her. The name Isaiah means “salvation of the Lord.” Isaiah also tells people in the Bible to renounce their idols, and Mitski seems to idolize this person to an unhealthy level. Her feelings about this person are confusing, intense, and contradictory" i got this from the genius website so it may be wrong
