First Turn to Hashem, Then to a Doctor

Chazal (Brachos 60A) learn from this pasuk that a doctor has permission to heal the sick. Sefer M’Zekeinim Esbonen quotes Rav Mordechai Chaim of Slonim zy”a as citing the verse (Yeshaya 44:6): “I am first and I am last, and besides for Me, there is no G-d”, and explaining in the name of Rav Dovid Lubliner zy”a that when most people get sick, they first go to a doctor and, if that doesn’t work, they daven to Hashem. The pasuk is saying that this should not be the case. Hashem should be first and last, and the doctor should only be secondary.
