(23) They came to Marah, but they could not drink the water of Marah because it was bitter; that is why it was named Marah.*Marah I.e., “bitter.” (24) And the people grumbled against Moses, saying, “What shall we drink?” (25) So he cried out to יהוה, and יהוה showed him a piece of wood; he threw it into the water and the water became sweet. There [God] made for them a fixed rule; there they were put to the test. (26) [God] said, “If you will heed your God יהוה diligently, doing what is upright in God’s sight, giving ear to God’s commandments and keeping all God’s laws, then I will not bring upon you any of the diseases that I brought upon the Egyptians, for I יהוה am your healer.”

(1) Miriam and Aaron spoke against Moses because of the Cushite woman he had taken [into his household as his wife]: “He took a Cushite woman!” (2) They said, “Has יהוה spoken only through Moses? Has [God] not spoken through us as well?” יהוה heard it. (3) Now Moses himself was very humble, more so than any other human being on earth. (4) Suddenly יהוה called to Moses, Aaron, and Miriam, “Come out, you three, to the Tent of Meeting.” So the three of them went out. (5) יהוה came down in a pillar of cloud, stopped at the entrance of the Tent, and called out, “Aaron and Miriam!” The two of them came forward; (6) and [God] said, “Hear these My words: When prophets of יהוה arise among you, I make Myself known to them in a vision, I speak with them in a dream. (7) Not so with My servant Moses; he is trusted throughout My household. (8) With him I speak mouth to mouth, plainly and not in riddles, and he beholds the likeness of יהוה. How then did you not shrink from speaking against My servant Moses!” (9) Still incensed with them, יהוה departed. (10) As the cloud withdrew from the Tent, there was Miriam stricken with snow-white scales!*scales Cf. Lev. 13.2–3. When Aaron turned toward Miriam, he saw that she was stricken with scales. (11) And Aaron said to Moses, “O my lord, account not to us the sin which we committed in our folly. (12) Let her not be like a stillbirth which emerges from its mother’s womb with half its flesh eaten away!” (13) So Moses cried out to יהוה, saying, “O God, pray heal her!” (14) But יהוה said to Moses, “If her father spat in her face, would she not bear her shame for seven days? Let her be shut out of camp for seven days, and then let her be readmitted.” (15) So Miriam was shut out of camp seven days; and the people did not march on until Miriam was readmitted. (16) After that the people set out from Hazeroth and encamped in the wilderness of Paran.
The text above demonstrates the ancient prospective that everything, health included, is in God's hands. Asa's decision to turn to physicians is criticized. It is important to note, however, that the criticism isn't that he turned to doctors but rather that he exclusively turned to doctors, neglecting the spiritual component of his health.
In Guide of the Perplexed 3:17, the 12th century rabbi and doctor Maimonides discusses a minor rabbinic opinion that people can sometimes go through “sufferings of love” whereby misfortunes befall an someone so that they will have a greater reward in the world to come.
(א) וירא אליו לְבַקֵר אֶת הֵחוֹלֶה אָמַר רַבָּי חָמָא בַּר חַנִינָא, יוֹם שְׁלִישִׁי לְמִילָתוֹ הָיָה, וּבָא הַקָּבָּ"ה וְשָׁאַל בִּשְׁלוֹמוֹ (בבא מציעא פ"ו):
(1) וירא אליו AND THE LORD APPEARED UNTO HIM to visit the sick man. R. Hama the son of Hanina said: it was the third day after his circumcision and the Holy One, blessed be He, came and enquired after the state of his health (Bava Metsia 86b)
(ד) רבי ברכיה בשם רבי לוי פתח ותתן לי מגן ישעך וימינך תסעדני וענותך תרבני (תהלים יח) כיון שנגלה עליו היה הקב"ה עומד ואברהם יושב שנאמר והוא יושב, ... בנוהג שבעולם כשהתלמיד חולה והרב הולך לבקרו התלמידים מהלכין תחלה ואומרים שליחות הרב לביתו של חולה לומר שהרב מבקש לבקרו. והקב"ה אינו כן כשמל אברהם והיה מצטער מן המילה אמר למלאכים לילך לבקרו, עד שהמלאכים הולכין קדמן הקדוש ברוך הוא שנאמר וירא אליו יקוק ואחר כך וישא עיניו וירא, יש עניו גדול מזה
Rabbi Brechia in the name of Rabbi Levi began his sermon thus, quoting the 18th Psalm."You make your saving help my shield, and your right hand sustains me. When God appeared to Abraham, God stood, and Abraham sat [as the verse states 'he was sitting in the doorway'.] It is the custom of the world than when a student is sick and the teacher goes to visit, others students go first and say, "There is a delegation of the to the house of the patient," meaning that the teacher wishes to visit the student. No so the Holy One. When Abraham was circumcised and was in pain from the circumcision, He tolf the messengers to go and visit. But before they arrived, God came in first, as the Torah says (Genesis 18:2), "And God appeared to him," and after that (Genesis 18:2) "And he lifted his eyes and saw three messengers."
Rabbi Acha said in the name of Rabbi Hanina. One who visits a paitient takes away a sixtieth of his pain. Said the [rabbis] to him: Is so let sixty people visit him and restore him to heath. He replied: The sixtieth is ts as the tenth spoken of in the scool of Rabbi (Judah the Prince. This means that a sixtieth of what remains is taken away, so there is an infinite regression.] It also provides that the visitor was a ben gilo- born under the same stars
