Judges 3:21 - Ellicott's Commentary On The Whole Bible

Thrust it into his belly. — This would involve certain, though not necessarily instant death. Josephus says, inaccurately, that he stabbed him to the heart (Antt. v. 4, § 2). The assassination is exactly similar to that of Henry III. of France, by the Dominican monk, Jacques Clement, who had provided himself with a commission from a friend of the king: “On Tuesday, Aug. 1, at 8 a.m.,” says L’Estoile, “he was told that a monk desired to speak with him. The king ordered him to be admitted. The monk entered, having in his sleeve a knife, unsheathed. He made a profound reverence to the king, who had just got up, and had nothing but a dressing-gown on, and presented him despatches from the Comte de Brienne, saying that he had further orders to tell the king privately something of importance. Then the king ordered those who were present to retire, and began reading the letter. The monk, seeing his attention engaged, drew his knife from his sleeve, and drove it right into the king’s small gut, below the navel, so home that he left the knife in the hole.” — Guizot, “Hist. of France,” iii. 479.
