This article treats the images and logic of Ps 58:4-9. Drawing on Stanley Tambiah's work on "performative analogies," it compares the images of serpents and unborn children as well as the ways in which these images are used in Ps 58 with incantations from SyroMesopotamia. It focuses on the similarities between Ps 58 and Syro-Mesopotamian incantatory traditions, emphasizing how the latter serves as a catalyst for understand ing Ps 58 as a YHWHistic religio-magical expression.
