After enduring the cruel hopes of enemies waiting for his death, the focus shifts to a deeply personal plea for God's mercy. This prayer stands in sharp contrast to the harsh words of the accusers. The suffering man asks God for healing and the strength to recover from his illness [מצודת דוד, ביאור שטיינזלץ]. This request serves as a direct response to the enemies who confidently claimed he would fall and never get back up [אבן עזרא, רד״ק]. Initially, the sick man might have already given up on his own life. However, witnessing the sheer wickedness of his enemies and their joy at his pain sparked a renewed will to live, driven by the realization that God would not allow such cruel people to celebrate his ruin [מלבי״ם].
The plea for healing is accompanied by a desire to repay these enemies, which raises a difficult moral question: is it right for a devoted, pious person to ask for recovery simply to seek revenge? [אלשיך]. Commentators approach this problem from several different angles. The primary approach among commentators is that the intention is straightforward, and he simply wishes to give them exactly what they deserve by returning their evil [מצודת דוד, ביאור שטיינזלץ].
Others soften this idea, suggesting the payback is not an active form of cruelty, but rather the withdrawal of kindness. In the past, he would pray, wear sackcloth, and mourn when his enemies fell ill. Now, he declares that he will no longer offer them this comfort when they face hardship [רד״ק]. Another perspective shifts the action away from the man himself, explaining that the payback is actually a strict punishment delivered by God. It is credited to the man only because his suffering is the underlying reason God is bringing justice upon the wrongdoers [מאירי]. Alternatively, the ultimate revenge is simply the recovery itself. The enemies will be forced to watch his success and recognize that God favors him, proving they have no power to cause him harm [מלבי״ם].
Finally, some interpretations completely flip the concept of payback into a positive action. One view suggests he wants to heal so he can continue his personal practice of repaying evil with acts of goodness [רב סעדיה גאון מובא ברד״ק]. A highly unique approach proposes that he actually wants to thank his enemies. According to this thought, it was precisely their terrible behavior that stirred God's mercy in the first place, ultimately leading to his rescue and recovery [אלשיך].
