In the Anselm Project Bible: The APB consistently presents the term as the personal name "Jonadab," while distinguishing him by the accompanying identification "son of Shimeah" in 2 Samuel and "son of Rechab" in Jeremiah. Those accompanying descriptions reflect the verse context rather than an added meaning of the name.
