Judges 9:20 Meaning and Commentary

Judges 9:20

But if not
If it appeared that they had not acted uprightly and sincerely in this matter:

let fire come out of Abimelech, and devour the men of Shechem, and the
house of Millo;
let wrath, rage, and fury, break out from Abimelech like fire, and issue in the destruction of those that made him king, both those of Shechem and of Millo:

and let fire come out from the men of Shechem, and from the house of
Millo, and devour Abimelech;
let them be incensed against Abimelech, and seek his ruin, and procure it: the sense is, that he wishes that strife, contention, and quarrels, might arise among them, and they mutually destroy each other; the words are imprecative of evil upon them both, and which had its exact fulfilment.
