Musar על ברכות 86:21

And one should be very careful not to shame any man for the Sages said: "He who whitens (shames) the face of another in public has no portion in the world to come" (Baba Mezià 59a). To whiten another's face is like murder, for the red departs and the white comes (thus one is spilling the blood of the shamed one within him) (Ibid., 58b). And the Sage said further: The pain of shame is worse than death. A person should allow himself to be burnt alive and not shame his fellow in public. And they learned this from Tamar who, even though they brought her forth to be burned, did not want to shame Judah (Berakoth 43b). And even when you are required to rebuke another the Torah says: "You shall surely rebuke your neighbor and not bear sin because of him" (Lev. 19:17). How shall you rebuke? At first, secretly and gently. However if you rebuke him at the beginning in public and shame him, then you have sinned because of this, (Arakin 16b). And this is all the more true where one shames another where no rebuke is called for.

This is precisely why that Mountain is called הר המוריה, since the קטורת, the best-beloved offering in the form of Isaac was offered there, and it is from there that G–d's responses are heard. The meal that Abraham had prepared for the angels also was the kind of קרבן of which Berachot 43 says: "which is the kind of thing that the soul derives pleasure from? it is ריח, fragrance."
