Шмот 21:19 Галаха: Mishneh Torah, One Who Injures a Person or Property, Mishneh Torah, Murderer and the Preservation, Kitzur Shulchan Arukh & Shulchan Arukh, Yoreh De'ah

And from where [do we know] that that which it states with regards to limbs, "An eye for an eye," is [to be understood as] payments? Since it is stated about it, "A wound for a wound," and it is explicitly stated, "And when a man strikes his neighbor with a stone or with a fist, etc... he should surely give him his rest and his rehabilitation." Behold, you have learned that "for (tachat)" mentioned with regards to a wound means payments. And this is [also] the case with "for (tachat)" mentioned concerning the eye and concerning the other limbs.

Wenn in der Tora steht: »An seiner Krücke עַל מִשְׁעַנְתּוֹ« (Ex. 21:19), so ist dies nicht so zu verstehen, als ob der Kranke an eine Krücke oder an eine Person gelehnt umhergeht, weil selbst ein tödlich Erkrankter im Stande ist, an eine Krücke gelehnt einherzugehen. Die Phrase »an seine Krücke« will also nur andeuten, dass der Kranke, durch sein eigene Kraft aufrecht gehalten, im Stande sei, ohne Beihilfe oder Stütze einherzugehen.

The Torah permits a doctor to heal the sick, as it is said "And he shall [pay] to have him healed properly."⁶Exodus 21:19. Therefore, a sick person should not rely on a miracle, but is obliged to follow the accepted procedure and call a physician to heal him. Many of the world's pious men have been cured by physicians. A person who refrains from calling in a physician (for himself) commits two wrongs: For one, it is forbidden to rely on a miracle in a life-threatening situation. This behavior causes one's sins to be remembered at a time of illness. Secondly, it is arrogant and presumptuous to rely on your righteousness that you will be healed in some miraculous manner. You should call the most competent physician but with all that, your heart should be turned to Heaven, and pray for mercy from the Faithful Healer, blessed is His Name trusting in Him alone.
