What is the only way we can be “holy”? What are some “bitter roots” that we may allow to grow up in us? Why couldn’t Esau bring about a change? How is this a warning to us? What is the difference between “Mt. Sinai” (a mountain to be touched) and “Mt. Zion”? How can it be that we “have come” to Mt. Zion / “are receiving an unshakeable kingdom” already? What is the “sprinkled blood and a better word than the blood of Abel”?
