It was on the eight day
Rabbi Yitzchok (Isaac) said: "Why is the á "Beth" open on one side, and closed on the other side"?
He offers the following answer: "When Man comes along in order to unite with the Torah, the open side of the á "Beth" indicates that the Torah is ready to receive him and to participate with him, meaning to co-operate with him".
However, when man closes his eyes and diverts from the Torah, walking away into another path, the Torah then conceals herself from the other side, resembling the right side of the á "Beth".
The following is expressed in Proverbs, thus: THE TORAH SAYS TO MAN: IF YOU WILL FORSAKE ME FOR ONE DAY, I WILL, IN TURN, MOVE AWAY FROM YOU THE DISTANCE OF TWO DAYS. MAN WILL NOT BE ABLE TO FIND HIS ENTRANCE TO THE TORAH UNTIL HE REPENTS AND BECOMES UNITED WITH THE TORAH, FACE TO FACE, AND THUS NOT ALLOW HIMSELF TO BE MOVED FROM THE TORAH ANY MORE.
THEREFORE, THE TORAH CALLS OUT TO MAN: TO YOU, MAN, I AM CALLING: "UNTO YOU, O MAN, I CALL; AND MY VOICE IS TO THE SONS OF MAN. SHE CRIETH IN THE CHIEF PLACE OF CONCOURSE, IN THE OPENING OF THE GATES, IN THE CITY SHE UTTERETH HER WORDS …"
211) Rabbi Yehuda said: The á "Beth" has the Image of two roofs and one line which unites them. We learn from this that one of the roofs points to heaven above, which is "Z.A"; whereas the other points toward the earth, which is "Malchut" (Kingdom). The Creator, who is "Yesod" (Foundation) is united with them and is receiving them.
Rabbi Elozor said: The first three upper lights are holy, that is, they are the three pillars which constitute one unity and make up the whole Torah. It is they who open the doors to all treasures, meaning that they bestow bounty to the "Emoonoh" ("Malchut").
The three pillars" house everything, which explains why they are called "House". It is because they are the three pillars of the "Beth", which refer to the three pillars relating to "Z.A". Thus, the three pillars are a house.
This is why the Torah begins with the letter á "Beth"; for the á "Beth" is actually the Torah and she is the healing balm of the world. Therefore, laboring in the Torah is tantamount to being occupied with the Holy Name.
212) We have learned that the whole Torah is actually an Upper Holy Name. Hence, inasmuch as the Torah is a Holy Name, she begins with the letter "Beth", which is the principle of the Holy Name; that is to say: The á "Beth" consists of the three letters called å "Vov".
The three "Vovin" of the initial letters of the three words "Vayiso", "Vayovey" and "Vayeit", which symbolize the three "Vovs" of pillars of "Z.A", constitute the three ties that bestow upon the "Emoonoh" ("Malchut").
213) Behold, all those who labor in the Torah are uniting with the Maker, and are crowned with the crowns of the Torah. They are beloved above and below.
GOD, stretches out His right hand to them, which is the light of "Chessed", (Mercy).

Isaiah 22:22
The key of the house of David I will lay on his shoulder; So he shall open, and no one shall shut; And he shall shut, and no one shall open.
Rev. 3:7
The three pillars which constitute one unity and make up the whole Torah. It is they who open the doors to all treasures, meaning that they bestow bounty to the "Emoonoh" ("Malchut").
The three pillars" house everything, which explains why they are called "House". It is because they are the three pillars of the "Beth", which refer to the three pillars relating to "Z.A". Thus, the three pillars are a house.
The Beit (Beth) is the first letter of the Torah, and since Hebrew is read right to left everything else proceeds from the house!
