Original: Samuel berates him for not carrying out the mass extermination completely, so Saul repents and begs Samuel to go with him. Samuel refuses and leaves, but Saul grabs at him, tearing part of Samuel's mantle, for which Samuel says that part of Saul's kingdom will be torn off and given to another.
Simplified: The first book of Samuel tells the history of Israel from the birth of Samuel until Saul 's death.
