Judges 9:52-53

9:52 Abimelech came and attacked the tower. When he approached the entrance of the tower to set it on fire, 9:53 a woman threw an upper millstone down on his head and shattered his skull.

sn A hand mill consisted of an upper stone and larger lower stone. One would turn the upper stone with a handle to grind the grain, which was placed between the stones. An upper millstone, which was typically about two inches thick and a foot or so in diameter, probably weighed 25-30 pounds (11.4-13.6 kg). See G. F. Moore, Judges (ICC), 268; C. F. Burney, Judges, 288.

tn Heb “Abimelech’s.” The proper name has been replaced by the pronoun “his” in the translation in keeping with conventions of English narrative style.
