A group of unsuspecting men arrive at the city, stepping directly into a carefully laid and brutal trap. Their arrival quickly turns into a scene of sudden violence, driven entirely by a killer's desperate need for self-preservation.
As soon as the men enter, they are slaughtered. The primary motive behind this massacre is strict concealment. Ishmael son of Nethaniah needed to keep the prior assassination of Gedaliah a complete secret. He feared that if these newly arrived men learned of the murder, the news would quickly spread, leading to a massive pursuit against him [מצודת דוד, ביאור שטיינזלץ].
To ensure the secret remains buried, the effort to hide the evidence continues immediately after the killings. The bodies are thrown into an existing pit that is already located on the premises [מצודת דוד]. This gruesome task, along with the massacre itself, is not carried out by Ishmael alone. He relies on the active participation of the men who are with him, acting together as a coordinated group to execute the murders and dispose of the evidence [מצודת דוד].
