Baanah is a figure mentioned in the Hebrew Bible, specifically in the context of the Davidic narrative. He is known as one of the sons of Rimmon the Beerothite and is noted for his involvement in the assassination of Ish-bosheth, the son of Saul. This act was part of the power struggles following the death of King Saul. In the biblical account, Baanah, along with his brother Rechab, sought to gain favor with King David by killing Ish-bosheth. However, their actions did not lead to the reward they anticipated; instead, David condemned their deed and executed them for their crime. This story highlights the complexities of loyalty and power during the early days of David's reign.
