SEV Biblia, Chapter 3:21
Mas Aod metió su mano izquierda, y tomó el cuchillo de su lado derecho, y se lo metió por el vientre;
John Gill's Bible Commentary
Ver. 21. And Ehud put forth his left hand, and took the dagger from his right thigh , etc.] Being, as before observed, a lefthanded man; ( Judges 3:15), and this he could the better do, without being taken notice of by the king, who, if he saw him move his left hand, would have no suspicion of his going to draw a dagger with it, and which also was hidden under his raiment, ( Judges 3:16); and thrust it into his belly ; Josephus says into his heart; it is certain the wound was mortal, and must have been in a part on which, life depended.
Matthew Henry Commentary
Verses 12-30 - When Israel sins again, God raises up a new oppressor. The Israelite did ill, and the Moabites did worse; yet because God punishes the sin of his own people in this world, Israel is weakened, and Moa strengthened against them. If lesser troubles do not do the work, God will send greater. When Israel prays again, God raises up Ehud. As judge, or minister of Divine justice, Ehud put to death Eglon, the kin of Moab, and thus executed the judgments of God upon him as an enemy to God and Israel. But the law of being subject to principalities an powers in all things lawful, is the rule of our conduct. No suc commissions are now given; to pretend to them is to blaspheme God Notice Ehud's address to Eglon. What message from God but a message of vengeance can a proud rebel expect? Such a message is contained in the word of God; his ministers are boldly to declare it, without fearin the frown, or respecting the persons of sinners. But, blessed be God they have to deliver a message of mercy and of free salvation; the message of vengeance belongs only to those who neglect the offers of grace. The consequence of this victory was, that the land had res eighty years. It was a great while for the land to rest; yet what is that to the saints' everlasting rest in the heavenly Canaan.
