20 And Ehud came to him, as he was sitting alone in his cool roof chamber. And Ehud said, "I have a message from God for you." And he arose from his seat. 21 And Ehud reached with his left hand, took the sword from his right thigh, and thrust it into his belly; 22 and the hilt also went in after the blade, and the fat closed over the blade, for he did not draw the sword out of his belly; and the dirt came out. 23 Then Ehud went out into the vestibule, and closed the doors of the roof chamber upon him, and locked them. 24 When he had gone, the servants came; and when they saw that the doors of the roof chamber were locked, they thought, "He is only relieving himself in the closet of the cool chamber." 25 And they waited till they were utterly at a loss; but when he still did not open the doors of the roof chamber, they took the key and opened them; and there lay their lord dead on the floor.

Commentary on Judges 3:12-30
(Read Judges 3:12-30)
When Israel sins again, God raises up a new oppressor. The Israelites did ill, and the Moabites did worse; yet because God punishes the sins of his own people in this world, Israel is weakened, and Moab strengthened against them. If lesser troubles do not do the work, God will send greater. When Israel prays again, God raises up Ehud. As a judge, or minister of Divine justice, Ehud put to death Eglon, the king 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 and powers in all things lawful, is the rule of our conduct. No such 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 fearing 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 rest 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.
