Likutei Moharan 41:2/ליקוטי מוהר"ן מ״א:ב׳

12. This is also a soul redemption, for the money is called pillars, as is written (Deuteronomy 11:6), “and all the subsistence at their feet.” Thus, when the tzaddik who performs the redemption places his hands on the money, he has in mind that there is “the great hand,” [“the strong hand” and “the exalted hand”]—i.e., the three hands. And three times YaD (hand) has a numerical value of forty-two.

2Now Shem Mem-Bet is comprised of seven names, with each name comprised of six letters. He should have in mind to draw <these> vavs —i.e., the seven names, each of which has vav letters—drawing them into the money, which is called pillars. Then it is called “vavey (the hooks of) the pillars.”

3These pillars—i.e., the feet, the heels—are an aspect of judgment. For twice Elohim has the same numerical value as EiKeV (heel), which is where the external forces have a hold. And judgment is only mitigated at its source. The root of judgment is in Binah, as is written (Zohar III, 10b): Judgment is aroused from Binah —<as is written,> “I am Binah, gevurah (strength) is mine” (Proverbs 8:14). And Shem Mem-Bet is in Binah.

4Consequently, when one draws Shem Mem-Bet <from Binah> into <the> pillars, the judgments are then mitigated at their source.

5This is the explanation of (Exodus 27:10), “the hooks of the pillars and their bands were silver.” The explanation is: By banding and joining vavey with the pillars silver is produced, <which is an aspect of> Chesed. <In other words,> the judgments are mitigated.
