Musar su Esodo 1:13

The Zohar, in commenting on the line יהי שם השם מבורך, (Job 1,21) divides the word מב-רך into מב =42, the name of the attribute of גבורה, i.e. that G–d had first planned to create the world based on מדת הדין הקשה. Subsequently, this attribute was softened through the co-option of the attribute of רחמים, mercy. After the first 42 letters, we have another 42 letters until the letter ר in the word ויאמר. This is followed by another 42 letters ending before the letter ד in ויבדל. The sign, סימן, of this sequence is ב-ה-ר-ד, with the letter ב referring to בראשית. You find a parallel in Israel's experience in Egypt, when the עבודה קשה, hard labour, was tempered by פה רך soft words, (Exodus 1,14) (the second time the expression פרך is used) The reason that this word also appears prior to עבודה קשה, is to remind us that the wicked are initially allowed to live in peace, only to face יסורים, afflictions, in the Hereafter. The opposite is true of the righteous whose experience in life begins with afflictions. G–d in His righteousness begins with מב i.e. the attribute of Justice, only to co-opt the attribute of Mercy, i.e. מצרף רך, at a later stage. This is why His name is blessed, i.e. מברך. Just as creation began with the מב, so the initial experience in Egypt which emanated from the wicked Pharaoh proceeded in the reverse order, i.e. commencing with פה רך, while ending in עבודה קשה.

לא תעשה כל מלאכה. There are thirty nine categories of work which are forbidden on the Sabbath. Rabbi Menachem Habavli writes that these categories correspond to the types of work the Israelites had to perform for the Egyptians during their years of bondage, i.e. the nnfl nnap mentioned in Exodus 1,13. When you look at the letters in the word עבודת פרך by using a method called את,בש,גר,דק, etc., you will find that the letters פ-ר-ך when exchanged with each other according to this method, when added together amount to 39. [compare Sanhedrin 22 on how Daniel deciphered the writing on the wall of Belshazzar's palace by using this method. Ed.] Thus far Rabbi Menachem Habavli. The Sabbath and the Exodus are part of the same utterance by G–d, as I have explained. The mystical dimension of the "private domain" on the Sabbath is that it must be a minimum of י (10) טפחים high and occupy an area of not less than ד (4 by 4) טפחים. 4 by 4 plus 10 equals the numerical value of the Ineffable Name י-ה-ו-ה=26.
