מדרש אויף תהילים 136:25

R. Elazar b. Abina said: "He who recites Te-hila l' David (Ps. 145) three times a day may be sure of an inheritance in the world to come." What is the reason? Shall I say because that particular chapter is arranged alphabetically? Then why not prefer chapter 119 Ps., which has an arrangement of eight repetitions of each letter of the alphabet? Is it because it has the verse Thou openeth Thy hand and satisfieth the demands of all Thy creatures. [it influences men to be benevolent]? If so, then why not the Great Hallel? in which also is written (Ib. 136, 25.) He giveth food to all flesh. Because Tehila l' David has the advantages of both; [is arranged alphabetically and influences men to be benevolent].

A king of flesh and blood, whilst at war, cannot supply all of his soldiers. Not so, the Holy One Blessed be He. "The L–rd is a man of war" — He wars against Egypt. "The L–rd is His name" — He sustains all who enter the world. As it is written (Psalms 136:13) "He divides the sea into strips" (twelve strips for twelve tribes) — (Ibid. 25) "He gives bread to all flesh." (Ibid. 147:10) He gives the beast its food, the raven's young, what they call for."

“In suffering you shall eat of it” – Rav Asi said: Earning a livelihood is twice as difficult as childbirth. Regarding childbirth it is written, “in pain [be’etzev] you shall give birth to children,” whereas regarding earning a livelihood it is written, “in suffering [be’itzavon] you shall eat of it.”³⁹Be’itzavon is an extended form of be’etzev, indicating a greater level of difficulty.
Rabbi Eliezer and Rabbi Shmuel bar Naḥman, Rabbi Eliezer said: Redemption is compared to earning a livelihood, and earning a livelihood to redemption, as it is stated: “He rescued us from our foes, for His kindness is forever,” (Psalms 136:24) and adjacent to that: “He gives food to all flesh, for His kindness is forever” (Psalms 136:25). Just as redemption is miraculous, so, too, earning a livelihood is miraculous. Just as earning a livelihood is every day, so, too, redemption is every day. Rabbi Shmuel bar Naḥman said: It [earning a livelihood] is even greater than redemption, as redemption is carried out through an angel, but livelihood is [directly] through the Holy One blessed be He. Redemption is carried out through an angel, from where is it derived? It is as it is stated: “The angel who redeems me from all evil” (Genesis 48:16). That livelihood is through the Holy One blessed be He? As it is stated: “You open Your hand, and satisfy the desire of every living thing” (Psalms 145:16). Rabbi Yehoshua ben Levi said: It [earning a livelihood] is greater than the splitting of the Red Sea, as it is stated: “Who split apart the Red Sea” (Psalms 136:13), and it says: “He gives food to all flesh…” (Psalms 136:25).⁴⁰Giving food to all flesh is mentioned after the splitting of the Red Sea, indicating that it is greater.
