People often try to avoid the heavy moral responsibility of saving others from danger or death. They might rely on claims of ignorance or a lack of ability to help. While these excuses might convince other people, they are completely meaningless before God, who pierces through any disguise and holds every person fully accountable for their choices.
A person might try to justify their inaction by insisting they simply did not know [רש"י]. The primary approach among commentators is that a person might deny reality, claiming they were unaware that others were in mortal danger or that they had no idea they possessed the power to save them. Beyond basic evasion, some offer more philosophical and spiritual justifications for refusing to help. A person might wonder why they should pray for the sick if heaven has already decreed their death, perhaps because they are wicked or destined to sin. Alternatively, one might question the value of breaking the Sabbath to save a dying person who has only an hour left to live. In a legal setting, a person might ask why they should make an effort to defend someone who has already been found guilty [אלשיך].
King Solomon answers all of these excuses by pointing out that God is present deep inside human hearts and understands their most hidden thoughts [מצודת ציון]. God comprehends these inner thoughts by deducing one idea from another, but He also possesses a clear, tangible knowledge of the absolute truth. Because He guards the soul, He sees exactly how a person's deeds are permanently engraved upon it [מלבי"ם].
This reality addresses all the moral doubts people raise to avoid taking action. God examines the true intention of the heart. If someone extends a dying person's life for even a brief time, that individual might use those final moments to repent and secure their place in the World to Come. Even if prayers for the sick do not work and the person passes away, God knows the prayer was offered with pure intentions for the good of the community. Regarding the justice system, a person must fulfill their duty to defend the accused. If a truly guilty person somehow escapes the court's punishment, God will ensure they receive their proper consequence through other means [אלשיך]. While human beings cannot know the complete web of thoughts that drive someone to act, God knows exactly if a person genuinely tried to do good to the best of their ability [רלב"ג].
Ultimately, putting on a false front is entirely useless before God [ביאור שטיינזלץ]. Divine justice operates measure for measure. If someone was aware of a danger but was simply too lazy to intervene, their own strength will eventually fail them [מצודת דוד, מלבי"ם]. On the other hand, God judges a person not merely by the final outcome of their efforts, but by the completeness of their intention. If someone acts with a pure and complete desire to save another, God will guard their soul and reward them for their noble effort, even if the rescue attempt ultimately fails [אלשיך].
