Midrash sa Mga Awit 103:1: Ein Yaakov (Glick Edition), Vayikra Rabbah & Midrash Tehillim

R. Shimi b. Ukba, and some say Mar Ukba, frequented the house of R. Simon b. Pazi., who was accustomed to arrange Agadah before R. Joshua b. Levi, and asked R. Simon b. Pazi: "What is the meaning of the passage (Ps. 103, 1.) Praise the Lord, O my soul, and all that is within me (praise) His Holy name." "Come and see,"' said R. Simon b. Pazi to him, "how the custom of the Holy One, praised be He! differs from the custom of frail man! The custom of frail man is to form a shape on the wall but he can put into it neither breath nor soul, nor entrails nor bowels, but the Holy One, praised be He! is not so. He forms a shape within a shape (creates a body within a body) and puts into it breath, soul, entrails and bowels, and it is this that Hannah means when she said (I Sam. 2, 2.) There is none holy like the Lord; for there is none besides Thee, and there is not any rock like our Lord. What is meant by Ein Tzur Keloheinu? It means that there is no shaper like our Lord." And what does it mean by For there is none besides Thee? R. Juda b. Menassya said: "Do not read Ein Biltecha (none besides Thee), but read Ein Lebalathecha (nothing could wear you out), for the nature of the Holy One, praised be He! is not like the nature of frail man. The works of frail man wear out their maker, but the Holy One, praised be He! is not so. He wears out his work." "You did not quite understand my question," said R. Shimi b. Ukba to R. Simon b. Pazi, "what I Intended to ask was this: Five times did David say Bless the Lord, O my soul; in reference to what was it said?" "He said it," [replied R. Simon b. Pazi] "in reference to the Holy One, praised be He! and in reference to the soul, for just as the Holy One, praised be He! filleth the entire world, so does the soul fill the entire body; just as the Holy One, praised be He! seeth, but cannot be seen, so does the soul see, but cannot be seen; just as the Holy One, praised be He! feedeth the entire world, so does the soul feed the entire body; just as the Holy One, praised be He! is pure, so is the soul pure; and just as the Holy One, praised be He! dwelleth in a place secret from all, so does the soul dwell in a secret place; therefore, let that (the soul) which possesses these five attributes come and praise Him, to whom these five attributes belong."

Rabbi Yoḥanan and Rabbi Yehoshua ben Levi, Rabbi Yoḥanan said: David said: “Bless the Lord, my soul” five times, corresponding to the five books of the Torah. Rabbi Yehoshua ben Levi said: Corresponding to the five worlds that a person sees. “Bless the Lord, my soul, and all that is within me bless His holy name” (Psalms 103:1); when one is located in his mother’s womb. “Bless the Lord, my soul, and do not forget all His acts of kindness” (Psalms 103:2); when he leaves his mother’s womb he says to [his soul]: Do not forget all the acts of kindness that He performed for you. “[Bless the Lord, all of His works, in all places of His dominion.] Bless the Lord, my soul” (Psalms 103:22); when a person reaches his stature²⁴As an adult. and emerges to engage in commerce. “Bless the Lord, my soul. Lord my God, You are greatly exalted” (Psalms 104:1); at the moment when a person passes from the world. And one in the future, “May sinners be eradicated from the earth, and may the wicked be no more. Bless the Lord, my soul. Halleluya” (Psalms 104:35).
Rabbi Shmuel bar Naḥman said in the name of Rabbi Yoḥanan: David recited one hundred and twenty psalms²⁵This is apparently an error, as this verse appears at the conclusion of Psalm 104. The Gemara in Berakhot 9b states: “David recited one hundred and three chapters, but did not recite Halleluya until he saw the downfall of the wicked.” and did not conclude them with Halleluya until he saw the downfall of the wicked, as it is stated: “May sinners be eradicated from the earth…[Halleluya].”

"Of David. Bless the Lord, O my soul." This is what the verse (Psalm 139:14) means when it says, "I will give thanks to You, for I am awesomely and wondrously made; Your works are wonderful, and my soul knows it well." Rabbi Avdimi son of Rabbi Nahman said: There is a bad thing that is good to acquire and a good thing that is bad to acquire. There are ten parts to a person: the throat for speaking, the esophagus for eating, the liver for getting angry, the lungs for breathing, the bile for jealousy, the stomach for sleeping, the intestines for grinding, the spleen for laughing, the kidneys for advising, and the heart for understanding. Therefore, David praised God and said, "I will give thanks to You, for I am awesomely and wondrously made." Therefore, bless the Lord, O my soul.
