The term "people" signifies all those temporarily separated from the holy ones due to their bondage to sin. The wording "of the people" is used instead of "on behalf of the people." Following this is an additional inscription: To David in the pillar-writing and other details, giving the psalm a dual focus.
Previously, regarding Psalm 83, it was mentioned that David, in evading Saul, traveled to the land of Gath to King Achish. Recognized by Achish’s men, he feigned madness out of fear. Due to his act of foolishness, the king set him free, and he was divinely salvaged from peril, as recounted in the first book of Kings, chapter 12. David then composed this psalm, which resonates not only with his personal tribulations at that time but also with the future struggles faced by the people of Judah. Acknowledging God’s grace, which granted him salvation, David inscribed this psalm as a lasting homage, akin to how some engrave words on stone or brass for eternal remembrance.
Gregory of Nyssa opines that this psalm can be recited on behalf of the church, which historically was distanced from the saints during its idolatrous practices and servitude to demons. Yet, it has now been liberated from spiritual adversaries through Him who is born of the lineage of David in the flesh, Christ. He fought on our behalf and inscribed our victory as if on a pillar. At that time, believers among the Gentiles also honored Him. Christ emerged from the borders of Judah, forming a community with the Gentiles, much like David in Ziklag, and uniting in a sacred marriage, having received into His throne one daughter from Israel and another from among the Gentiles—representing the church composed of both Jews and Gentiles.
This psalm additionally addresses the Jews in relation to Christ. Eusebius notes that David visited Achish, king of Gath, on two occasions: the first, when he pretended to be mad to escape danger, and the second, when Achish welcomed him and granted him the settlement of Ziklag, where he lived for four months with 600 men and their families, as documented in 1 Samuel, chapter 27. Thus, it appears that this psalm is articulated by David not during his initial visit to Achish when he feigned insanity, leading to the writing of Psalm 33, but during his subsequent visit when the foreigners provided him a place to remain in his homeland, as previously noted by Eusebius.
