A key - literally, "an opener." Probably a wooden instrument with which they either lifted up the latch within, or drew back the wooden bar or bolt. The chief officer of Eglon's household probably had a second key (compare Isaiah 22:15, Isaiah 22:20-22; Isaiah 37:2).

And they tarried until they were ashamed,.... And knew not what to think of it, or what methods to take to be satisfied of the truth of the matter, and what should be the meaning of the doors being kept locked so long:

and, behold, he opened not the doors of the parlour; this was what surprised them, and threw them into this confusion of mind, that they knew not what course to take for fear of incurring the king's displeasure, and yet wondered the doors were not opened for so long a time:

therefore they took a key and opened them; this is the first time we read of a key, which only signifies something to open with; and the keys of the ancients were different from those of ours; they were somewhat like a crooked sickle (i), which they put in through a hole in the door, and with it could draw on or draw back a bolt, and so could lock or unlock with inside, see Sol 5:4; and at this day the keys in the eastern countries are unlike ours. Chardin (k) says, that a lock among the eastern people is like a little harrow, which enters half way into a wooden staple, and the key is a wooden handle with points at the end of it, which are pushed into the staple, and so raise this little harrow:

and, behold, their lord was fallen dead on the earth; lay prostrate on the floor of the parlour, dead.

(i) , Homer. Odyss. 21. ver. 6. & Eustathius in ib. (k) Apud Calmet's Dictionary, on the word "Key".

And they tarried till they were ashamed: and, behold, he opened not the doors of the parlor; therefore they took a key, and opened them: and, behold, their lord was fallen down dead on the earth.

3:25 Ashamed - Or, confounded, not knowing what to say or think; lest they should either disturb him, or be guilty of neglect towards him. A key - Another key, it being usual in princes courts to have divers keys for the same door.

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.
