Midrash su Salmi 119:91

R. Alexandri said in the name of R. Chiya b. Abba: "The miracle that is done for a sick person is much greater than the miracle wrought unto Chanania, Mishael and Azariah; for, at the miracle of Chanania, Mishael and Azariah it was an ordinary lire that could be quenched by all; but the fire that is within a sick person is a heavenly fire and can not be quenched." A. Alexandria said further in the name of R. Chiya b. Abba, according to others in the name of R. Joshua b. Levi: "As soon as the end of a man approaches, everything rules over him, as it is said (Gen. 4, 14) It will come to pass that everyone who findeth me will slay me." Raba said that we infer it from the following (Ps. 119, 91) They stand this day according to Thine ordinances; for all things are Thy servants. The Rabbis related to Rabba b. Shila that a certain tall man died while riding on a little mule, and as he approached the bridge the mule became wild and threw him off into the river, which caused his death. Rabba b. Shila applied to that man the above-quoted passage. They stand, this day, etc. Samuel saw how a snake was carried upon the back of a frog to enable it to pass a stream and bit a person who died of the bite. Samuel applied to that man the above quoted passage. They stand, etc.

Thou hast established the earth, and it standeth. They stand this day according to Thine ordinances (ibid.). It was according to Your ordinances that You created everything, as is said: In the beginning God created (Gen. 1:1). Another comment on They stand this day according to Thine ordinances. Even this day was brought forth according to Your ordinances, as it is said: Every morning, every morning doth He bring His ordinance to light (Zeph. 3:5). They stand this day according to Thine ordinances; they shall perish, but Thou shalt stand (Ps. 102:27), for You are the foundation of the world. Another explanation of But Thou shalt stand is that You shall cause others to stand. Another comment on And it standeth according to thine ordinances. That is, according to the words You spoke to Aaron (that) the priesthood would be firmly established through him.
