Rashi on Exodus - The Patriarchs and Those Who are Lost and Not Found

"Moses returned to Hashem and said, 'My Lord, why have You harmed this people, why have You sent me? From the time I came to Pharaoh to speak in Your Name he harmed this people, but You did not rescue Your people."

-- Exodus 5:22


"The Holy One, Blessed is He, said to Moses in response: Woe! For those who are lost and are not found! I have good cause to bemoan the death of the Patriarchs. Many times I revealed Myself to them as El Shaddai, yet they did not say to Me, 'What is Your Name?' But you said, 'If they will say to me, What is His Name, what shall I say to them?'"

-- Rashi, Commentary on Exodus


LOST : Because they did not enter the promised land.

NOT FOUND : They did not find what Moses found when he asked for the Name to be revealed to him.

Rashi on a Reference to Metatron in Exodus 23:21 - "My Name is Within Him"

"Behold! I send an angel before you to protect you on the way, and to bring you to the place that I have prepared.  Beware of him ─ hearken to his voice, do not disobey him, for he will not forgive your transgression ─ for My Name is within him."

-- Exodus 23:20-21

"Our Rabbis have said that this is the angel Metatron, whose name is like the Name of his Master, in that the numerical value of Metatron (314) equals that of Shaddai."

-- Rashi, Commentary on Exodus

Midrash Rabbah Shemot on Prayer and Reciting Words of Torah

"Anyone who does the Will of the Omnipresent and directs his mind in prayer, God listens to him in this world, and so too in the World to Come; for it is stated, 'It will be that before they call I will answer' (Isaiah 65:24) ─ in this world, 'while they speak, I will hear' (ibid.) ─ in the World to Come.
"And what will they speak in the World to Come? The explanation is that in the World to Come every person will stand and make his Torah learning heard, and God will sit and make His Torah heard with them, as it is stated, 'Then those who fear haShem spoke to one another, and haShem listened' (Malachi 3:16). And it is written, 'And your eyes will behold your Teacher and your ears will listen' (Isaiah 30:20-21); and 'All your children will be students of haShem' (ibid. 54:13)."

-- Midrash Rabbah, Shemot 21.3
