Pri Tzadik , Shemos 6

Moses said to God, “When I come to the Israelites and say to them, ‘The God of your fathers’ [house] has sent me to you,’ and they ask me, ‘What is [God’s] name?’ what shall I say to them?”

And God said to Moses, “Ehyeh-Asher-Ehyeh,” continuing, “Thus shall you say to the Israelites, ‘Ehyeh sent me to you.’”

AND THEY SHALL HEARKEN TO THY VOICE. “I.e., of their own accord. As soon as you will mention to them this expression, [namely, the double use of the word pakod — pakod pakad’ti (I have surely remembered), mentioned in Verse 16], they will immediately hearken to your voice for they have long had this sign as a tradition from Jacob and Joseph, that by use of this expression they will be delivered [from Egypt]. Jacob said to them, and G-d will surely remember you, and Joseph said to them, G-d will surely remember you.” Thus the language of Rashi. Perhaps Rashi will explain that Joseph used this expression twice in order to affirm that it was a tradition he received from his father.And in Eileh Shemoth Rabbah, the Rabbis said: “[As soon as you will say to them pakod pakad’ti], they will immediately hearken to your voice. Why? It is because they have a tradition of the words [wherein G-d will announce the approaching redemption], so that the redeemer who will come and mention to them this double p’kidah [remembrance] is the true redeemer.” Thus the language of the Rabbis on this Agadah.Now you may ask: Why should they listen to Moses? Perhaps he heard this tradition as well as they did. In reply it may be said that thus they received the tradition from Joseph, who heard it from their father the prophet: the first person who will come and announce the message with this expression [pakod pakad’ti] will be the one who will deliver them [from Egypt], it being revealed and known before the Holy One, blessed be He, that no man will come and deceive them. This He promised them.But in another place in the Midrash I found: “Said Rabbi Chama the son of Rabbi Chanina: ‘When Moses was in his twelfth year, he was torn up from his father’s house. Why? Had he grown up in his father’s house, the children of Israel would not have believed in him when he came and told them these things. They would have said that his father handed him over these words, as Joseph had handed them over to Levi, and Levi to Kohath, and Kohath to Amram. This was why he was torn up from his father’s house, and when he came and told Israel all the words, they therefore believed him, as it is said, And the people believed.’” The intent of the Rabbis’ words that Joseph handed it over to Levi [and as to why Jacob did not reveal it directly to Levi] is that Jacob revealed the secret to Joseph because of his love for him. With this very same language Joseph made all his brothers swear, and he revealed it to Levi. He told them that he gave this [as a secret to Levi] on account of the tradition he received from his father [not to reveal it], and he commanded that the matter remain a secret.

As face answers to face in water,So does one man’s heart to another.

As in water the face that you show it, it shows you.

is the heart of a man to a man his friend. According to how much a man knows that his friend loves him, so he will show him his face.

And [God] said, “I will be with you; that shall be your sign that it was I who sent you. And when you have freed the people from Egypt, you shall worship God at this mountain.”

Rabbi Eliezer said: The five letters of the Torah, which alone of all the letters in the Torah are of double (shape), all appertain to the mystery of the Redemption. With "Khaph" "Khaph" our father Abraham was redeemed from Ur of the Chaldees, as it is said, (Lekh Lekha) "Get thee out of thy country, and from thy kindred… unto the land that I will shew thee" (Gen. 12:1). With "Mem" "Mem" our father Isaac was redeemed from the land of the Philistines, as it is said, "Go from us: for thou art much mightier (Memennu M'ôd) than we" (Gen. 26:16). With "Nun" "Nun" our father Jacob was redeemed from the hand of Esau, as it is said, "Deliver me, I pray thee, (Hazilêne na) from the hand of my brother, from the hand of Esau" (Gen. 32:11). With "Pê" "Pê" Israel was redeemed from Egypt, as it is said, "I have surely visited you, (Paḳôd Paḳadti) and (seen) that which is done to you in Egypt, and I have said, I will bring you up out of the affliction of Egypt" (Ex. 3:16, 17). With "Zaddi" "Zaddi" the Holy One, blessed be He, in the future will redeem Israel from the oppression of the kingdoms, and He will say to them, I have caused a branch to spring forth for you, as it is said, "Behold, the man whose name is (Zemach) the Branch; and he shall grow up (yizmach) || out of his place, and he shall build the temple of the Lord" (Zech. 6:12). These letters were delivered only to our father Abraham. Our father Abraham delivered them to Isaac, and Isaac (delivered them) to Jacob, and Jacob delivered the mystery of the Redemption to Joseph, as it is said, "But God will surely visit (Paḳôd yiphḳôd) you" (Gen. 1. 24). Joseph his son delivered the secret of the Redemption to his brethren. Asher, the son of Jacob, delivered the mystery of the Redemption to Serach his daughter. When Moses and Aaron came to the elders of Israel and performed the signs in their sight, the elders of Israel went to Serach, the daughter of Asher, and they said to her: A certain man has come, and he has performed signs in our sight, thus and thus. She said to them: There is no reality in the signs. They said to her: He said "Paḳôd yiphḳôd"—"God will surely visit you" (ibid.). She said to them: He is the man who will redeem Israel in the future from Egypt, for thus did I hear, ("Paḳôd Paḳadti") "I have surely visited you" (Ex. 3:16). Forthwith the people believed in their God and in His messenger, as it is said, "And the people believed, and when they heard that the Lord had visited the children of Israel" (Ex. 4:31).

“And it shall be when I bring clouds over the earth, then the rainbow will appear in the cloud.” (Bereshit, 9:14)“Cloud” signifies fear and the concealment of His presence. “Rainbow” (or simply “bow”) signifies a stronghold. That is to say with powerful fear you shall find great security, and this is what the Holy One, blessed be He, promised Noach. This is as it is said in the holy Zohar (Bereshit, 72b), “do not expect the heels [arrival] of the Messiah until you see the luminous colors of the rainbow.” This means that once the great strengths of God are apparent and explicit before your eyes, then you may expect the arrival of the Messiah. We find this in the question of R. Shimon bar Yochai to R. Yehoshua ben Levi (Ketubot, 77b):As Yehoshua ben Levi proceeded on his way he found R. Shimon bar Yochai sitting on thirteen tables of gold. “Are you,” R. Shimon asked him, “the son of Levi?” “Yes,” he replied. “Has a rainbow ever appeared in your lifetime?” “Yes,” he replied. “If that is true then you are not the son of Levi” (the rainbow was a sign that God would never again destroy the world, which should not have been necessary in the generation of a Tsaddik such as Yehoshua ben Levi. as the Tsaddik’s merits alone should be enough to save the generation. See Rashi). But truly a rainbow had not appeared in his lifetime, but he thought, “I do not want to take the credit for myself.”Rabbi Shimon specifically asked him, “has the rainbow appeared [“nirata,” just as it is worded in the verse],” and not “have you seen [ra’ita],” for the meaning of “appeared” means occasionally but not constantly. Yet for Rebbi Shimon, the rainbow appeared constantly. The rainbow and the great strength of Israel is the “Shema’ Yisroel - Hear O Israel,” which gives strength to the hearts of those who yearn for His mercies.
