Some Edits

I edited this post. It now contains the secret יהי אור as we discussed. So, it refers to 127/1, 274/2, 288/2, 351/2, 420/2, 703/4, as well as to 464/2. The title, with words of the same Pasuk, refers to the secret of 410-417-420, which is the secret of 507, as well as to 704, the cosmic number. A good thing to know by heart.

I also prefixed the story of Ya'akov with the phrase

וַיֶּאֱהַב יַעֲקֹב, אֶת-רָחֵל

improving the flow of the story. I moved up the sentence:

הַשָּׂדֶה אֲשֶׁר-קָנָה אַבְרָהָם, מֵאֵת בְּנֵי-חֵת--שָׁמָּה קֻבַּר אַבְרָהָם, וְשָׂרָה אִשְׁתּוֹ

As a result, מֵאֵת בְּנֵי-חֵת becomes an inclusio of the story of the burial of Avraham, instead of a rather awkward repetition of phrases. The whole inclusio is now made into a separate section; a reconstruction of how P_E "must have" had it. Things got messed up when P_E was merged with P.
