and as strong as a lower millstone This clause is repetitious, meaning that his heart is as basic and permanent as the millstone that is placed under the upper millstone, for the upper millstone revolves and rotates and grinds, whereas the lower one does not move from its place because it is fastened to its place, so that it should not move. That is called פֶּלַח [רֶכֶב] as it is stated (Jud. 9:53): “And a certain woman cast an upper millstone: פֶּלַח רֶכֶב, upon Abimelech’s head.” The lower one is called פֶלַח תַּחתִּית the lower piece.

The son of Yerubeshes. This is Gidon who fought with Boshes, which is the Baal.3See Shoftim 6:32. The name יְרֻבֶּשֶׁת is a contraction of the two words, יָרֶב and בָשֶת, fighting with Boshes. Avimelech’s death, referred to here, is related in Shoftim 9:53.
Rashi
and he who rolls a stone He rolls it from place to place so that people will stumble on it. The Aggadah (Tanhuma Buber, Vayera 28, see footnote 157) interprets it in reference to Abimelech, who slew his seventy brothers on one stone and his end was that he died by a stone, as it is said (Jud. 9:53): “And a certain woman cast a piece of an upper millstone upon Abimelech’s head and crushed his skull.”
