DEUT294 All the areas of trust in the Holy One Blessed be He are eight: (1) The matter of a man's body in itself; One must surrender himself and give himself up to His great mercies. He must realize that he is without counsel or conduct without His permission and decree. But though the proper functioning of his limbs and the length of his days are dependent upon the Blessed One's decree, still one must bestir himself to gain all his needs, to restore his life, and to provide remedies for himself. Nevertheless, he must for us to God to heal him and realize that the doctor and the cure are being sent to him by the Blessed One. He must rely in this on God alone and ascribe to Him the ability and the power. And let one not say: "Since all depends on the Blessed Creator's decree, I will walk in ways of danger and drink poison!" Do we not find that Shemuel said (I Shemuel 16:2): "How can I go? If Saul hears, he will kill me!" And, still, he was not considered as lacking in trust, and the Holy One Blessed be He answered him (ibid.): "Take a heifer with you and say, ' I have come to sacrifice to Hashem.'" Of one who places himself in danger and says, "I trust to Hashem," it is written (Mishlei 14:16): "And the fool passes on [into danger] and is confident." Torah has exhorted us against this [this verse]: "Do not try Hashem your God." If one places himself in danger and dies as a result, his punishment is greater than if he kills another.
