A leader facing exile attempts to dissuade a loyal supporter from joining a dangerous and uncertain escape. Rather than pulling his allies into his own misfortune, David presents logical arguments to spare them from unnecessary hardship, ending with a deep appreciation for their willingness to stand by him. He first points out that the follower only recently arrived from Gath to offer his service [מצודת דוד, ביאור שטיינזלץ, אברבנאל]. Because of this recent arrival, David feels it is unfair to immediately drag him into a tiring and restless journey [מלבי״ם, ביאור שטיינזלץ].
Furthermore, the nature of this flight is entirely unpredictable. David explains that he is not marching toward a known destination. Instead, he is a fugitive forced to wander wherever chance takes him, entirely unable to offer anyone a safe shelter [רש״י, רד״ק, מצודת דוד, אברבנאל]. Given this bleak reality, David urges his supporter to return home and take along his companions, the six hundred men from Gath who accompanied him [רד״ק, מצודת ציון, ביאור שטיינזלץ].
As they part ways, David expresses a profound sentiment of kindness and truth. The primary approach among commentators is that this serves as a deep expression of gratitude. David acknowledges his friend's good intentions, viewing the sheer readiness to join him in exile as a genuine act of kindness, strengthened by truth [רש״י, רד״ק, מצודת דוד, מצודת ציון]. Others see this sentiment as a conditional promise for the future. David means that if God safely restores him to his throne, He will faithfully repay this loyalty, which represents the truth. However, if he does not survive the ordeal, the supporter's readiness to help will remain an act of pure kindness that can never be repaid [אברבנאל]. Alternatively, some suggest that David is reminding the commander of his duty to his own soldiers. In this view, the call for kindness and truth is a request for the leader to care for his men by taking them back, thereby sparing them the bitter hardships of life on the run [מלבי״ם, רד״ק].
