Albert Barnes Commentary Jeremiah 50:29

"Call together the archers against Babylon, all them that bend the bow; encamp against her round about; let none thereof escape: recompense her according to her work; according to all that she hath done, do unto her; for she hath been proud against Jehovah, against the Holy One of Israel." — Jeremiah 50:29 (ASV)

Or, Summon the archers to Babylon, even all who bend the bow: encamp against her.... In this portion of the prophecy, the capture of Babylon is regarded as the punishment due to her for burning the temple (Jeremiah 50:28).
