In the book of Judges, the prophetess Deborah, after joining with Barak to lead the Israelites to victory over the army of the Canaanite general Sisera, utters a lengthy poem that recaps the events told in prose in the previous chapter. Michelle Knight uses this passage to illuminate the way the Hebrew Bible employs poetry. Contrary to the widespread and questionable 21st-century assumption that pairs verse with emotion and prose with reason, the Song of Deborah is, Knight argues, a work of theology as much as it is an aesthetic expression of the joy of salvation:
The rhetorical power of the Song of Deborah and Barak is undeniable. Its imagery is at times poignant, and at others uplifting. The poet celebrates, laments, and criticizes, using every tool at her disposal to draw the audience in to her appraisal of the battle, including, but not limited to, emotional appeals (e.g., 5:21: “March on, my soul, with might!”). However, the song is far from a simple emotive retelling of a stirring story. Instead, as a prophetic voice with the authority of a divine emissary, Deborah (with Barak) reinterprets the events that had just transpired to address a theological shortsightedness among the Hebrews.
Barak, like Gideon after him, was under the faulty impression that it would be under his leadership and on the field of battle, by means of the talents of his army and the weapons they wielded, that Israel would secure victory. Deborah corrected this perspective twice: prospectively, in her clarification that it would be in a completely different location and by a different hand that the Lord would bring victory (4:9), and then retrospectively, in the form of a song.
It is the unique quality of Hebrew poetry—its images, repetition, terseness, and lexical freedom—that best clarifies the state of affairs after the [battle against the Canaanites]. Simultaneously celebratory and convicting, this poem says explicitly what narrative can only intimate and argues forcefully what prose can only state. [The song] is evocative, certainly, but its aim is a shift in theological reasoning.
