תהלים, פרק מ׳, פסוק י״ב

After expressing deep gratitude for past rescue, the focus naturally shifts toward the future, driven by a clear understanding that a person always needs divine guidance. The prayer transitions into a heartfelt plea for God to never hold back His mercy, alongside a statement of trust that His kindness and the truth of His promises will serve as a constant shield [רש״י, שטיינזלץ, מצודת דוד]. The primary approach among commentators is that this request comes from a profound realization of human dependence. Just as God delivered him from previous hardships, he prays for ongoing protection so that God's mercy never leaves him [רד״ק, מאירי].

Some view this dynamic as a call for a mutual relationship. Since he has openly thanked God and shared His praises with others, he asks God to respond by continuing to shower him with compassion [מצודת דוד]. Furthermore, the very kindness and truth that he just publicly declared to the masses are the exact forces that will now stand by him and protect him from future troubles [אבן עזרא].

A deeper look reveals a careful distinction between the different divine qualities at play. The attribute of mercy generally requires a person to have a certain level of merit to be awakened. Because of this, there is an explicit prayer asking that mercy not be withheld. On the other hand, kindness and truth operate independently of human merit. For this reason, there is no need to ask for them; instead, there is a confident declaration that they will always provide protection. Another perspective suggests that the plea for mercy is actually a specific request regarding how these gifts are given. It is a prayer that God's kindness and truth be granted as an entirely free gift, without deducting from any of the person's earned merits [אלשיך].
