A desperate cry to God is born out of absolute dependence and profound helplessness. When faced with a deep crisis, a person realizes there is no other refuge, turning exclusively to the Creator for mercy.
Often, an individual might feel unworthy to ask for help with personal troubles, knowing they do not deserve salvation based on strict justice. Yet, the very act of submitting and admitting this unworthiness is what awakens God's mercy, allowing the person to ask for His kindness as a completely free gift [חומת אנך]. This realization stems from the understanding that there is simply no other way out; there is nothing left to do but call out to God [אבן עזרא].
This appeal is entirely exclusive. The plea for help is directed solely toward God, without relying on any other power or earthly helper [רד״ק, מאירי]. While it is a general request for grace, it can also be understood as a highly specific, urgent plea to save one's physical body from the threat of death [אלשיך].
On a deeper level, this continuous cry addresses a profound spiritual dynamic. Sometimes, God delays saving righteous people simply because He desires to hear their prayers. Aware of this, the petitioner asks God to respond immediately and not hold back His salvation just to keep hearing the prayer. In return, a sincere promise is made: even if God answers right away, the prayers will not cease, and the ongoing conversation with Him will continue [אלשיך].
The primary approach among commentators is that this ongoing prayer represents a constant, continuous action, taking place at all times. In contrast, an allegorical perspective views this enduring cry as a hint to the long period of exile. This era is experienced as a bright, prosperous day for the nations of the world, but for the people of Israel, it is lived as a long and dark night [רש״י].
