Shared ground
Jeremiah 15:15–18 is a first-person prayer in which the prophet brings his distress straight to Yahweh. The text explicitly presents Jeremiah as under pressure from “persecutors,” and he asks God to remember him, come to his aid, and act against those who attack him. He fears being “taken away” while God is being patient.
The passage also explicitly links Jeremiah’s inner life to God’s speech: God’s “words” are pictured as something he “ate,” meaning he took them in so deeply that they became his joy and part of his identity (he is “called by” Yahweh’s name). At the same time, this calling isolates him. He does not join the happy crowd; he “sat alone because of [God’s] hand,” and he is filled with indignation.
Finally, the passage openly includes complaint. Jeremiah describes ongoing pain and an unhealed wound, and he dares to ask whether God will be like a stream that looks promising but fails when needed.
Where interpretation differs (only where needed)
One key question is what Jeremiah is asking for when he says “avenge me.” Some readers take it as a request for fair justice—God to set things right against violent or unjust attackers. Others hear a more personal edge—Jeremiah wanting his opponents to suffer back, even if he frames it in prayer.
Another question is what “don’t take me away” means. Some understand it mainly as protection from death. Others think it could include removal from his post, loss of influence, or being swept away in the collapse that is coming.
A third question is how sharp Jeremiah’s last line is. Some read “deceitful brook” as a bold accusation that God has become unreliable. Others read it as a grief-driven question that stays within covenant language: Jeremiah is not denying God, but describing how God’s delay feels from inside prolonged suffering.
Why the disagreement exists
The passage uses compressed, emotional prayer-language rather than careful definitions. Words like “avenge,” images like “eat,” and metaphors like a failing stream can carry more than one shade of meaning. Also, the text moves quickly from trust (“your words… my joy”) to protest (“waters that fail”), so interpreters differ on how to weigh those notes together.
What this passage clearly contributes
Explicitly, it shows that Jeremiah’s prophetic calling involves both deep attachment to God’s message and real social and physical cost. It also shows that biblical prayer can include protest and strong questions without pretending suffering is small.
By theological inference, the passage suggests a relationship in which God’s servant expects God to act consistently with God’s name and calling, and therefore feels the pain of delay as a crisis of trust. The text does not resolve the tension here; it records the tension as part of Jeremiah’s lived faithfulness and distress.
