The Philistines are referenced in the Book of Mormon as part of quotations from the prophetic writings of Isaiah, which were included by Nephi, one of the prophets and leaders among the people of Lehi who had emigrated from Jerusalem to the Promised Land. Their mention in the Book of Mormon text serves to highlight behaviors and outcomes that parallel the larger narrative and teachings of the Nephite culture and its interactions with the Lord.
In a rebuke of the house of Jacob, the people are condemned for practices likened unto the Philistines, suggesting a turning from God and an embrace of heathen customs, including soothsaying and alliances with foreigners (2 Nephi 12:6). This comparison emphasizes the departure of the house of Jacob from their covenantal commitments to the Lord. Furthermore, in prophetic foresight referring to the judgment and challenges to be faced by Israel, the Philistines are depicted symbolically at the rear of Israel, poised to consume them (2 Nephi 19:12), signaling the encompassing threats and continual adversities that would confront the Israelite people.
Additionally, it is prophesied that those of the covenant, presumably the Israelites or Nephites, will have dominion over their adversaries, illustrated by them flying upon the shoulders of the Philistines (2 Nephi 21:14). This imagery conveys a future triumph of God’s people over their enemies, echoing themes of deliverance and divine assistance found throughout scripture.
Through these passages, the Philistines serve as a rhetorical and prophetic device within the Book of Mormon, symbolizing the spiritual dangers of apostasy, the consequences of sin, and ultimately the assured victory of the Lord’s covenant people over their obstacles.
