Following grand displays of cosmic power and sweeping storms, the focus shifts to a deeply personal and intimate dimension. God reaches down from heaven to pull a person out of a drowning danger [ביאור שטיינזלץ]. The primary approach among commentators is that this reaching from above represents God's direct assistance, or His angels, sent to rescue a person from surrounding enemies [רש״י, אבן עזרא, מצודת דוד]. The act of being drawn out from the depths mirrors the very name of Moses, who was famously pulled from the river [רש״י, מצודת ציון, מלבי ם באור המילות]. In this context, the deep waters serve as a metaphor for overwhelming troubles, specifically numerous pursuing enemies who threaten to wash over and drown a person like a rushing river [רד״ק, אבן עזרא, מצודת דוד].
The nature of this divine rescue is understood through two distinct lenses. From a national and historical perspective, the rescue hints at the miracles God performed for the Israelites, such as sending angels to save them from the Egyptians at the parting of the Red Sea [רש״י]. Some connect this directly to King David's royal lineage, explaining that God preserved his ancestry by saving Lot from Sodom and drawing his forefathers through the sea by the merit of Nahshon, who boldly stepped into the water until it reached his nose [אלשיך]. In contrast, the central approach views the rescue as a literal, personal account of David's own battles. According to this view, deliverance from the waters happens in two ways. Sometimes, God dries up the water entirely, completely defeating the enemies. Other times, He simply lifts the drowning person out of immediate danger without destroying the pursuers, just as David was rescued from King Saul during a narrow escape at the Rock of Escapes [רד״ק].
This deliverance is not a single, brief moment but an ongoing process. The enemies are compared to people standing on a riverbank, waiting for the survivor to emerge so they can push him back in and drown him again. Because the danger persists, God does not merely pull the person out of the water. He continues to watch over him, actively extracting him from their hands and guiding him into a wide, safe space where those enemies can no longer cause harm [מלבי״ם].
