“At my stumbling
They gathered in glee.
They gathered together against me.
Ruffians whom I did not know
Tore at me without ceasing.
They impiously mocked more and more.
They gnashed at me with their teeth.”
Whenever David stumbled, these pursuers gathered in glee around him. People he did not know tore into him non-stop. They mocked him. They gnashed at him with their teeth. These are pretty graphic details about David’s enemies and what they were trying to do to him.
