Summary
Although divided by a chapter division in our English translations, Psalms 42 and 43 should be read as single song, a powerful lament by which Israel’s covenant LORD is called upon to send forth his light and truth (43:3). This plea for light and truth finds its proximate fulfillment already in the immediate subsequent Psalms, a group of Psalms which opens Book 2 of the Psalter with the common inscription, “of the sons of Korah.” The ultimate fulfillment of the plea for light and truth is found in the dual advents of Jesus Christ, who is “the Light of the World” and “the Truth.”
