He covereth his feet - Compare the marginal references. The explanation of the phrase as "taking sleep" suits both passages best.

He covereth his feet - He has lain down on his sofa in order to sleep; when this was done they dropped their slippers, lifted up their feet, and covered them with their long loose garments. But the versions, in general, seem to understand it as implying a certain natural act.

When he was gone out, his servants came,.... When Ehud was gone through the porch, and out of the palace, the servants of Eglon, who had been put out, came to the parlour door to reassume their former place, and finish their business with the king, or in order to wait upon him as usual:

and when they saw that behold the doors of the parlour were locked; which they supposed were done by the king himself with inside, having no suspicion of Ehud:

they said, surely, or "perhaps", as Noldius (f) renders it:

he covereth his feet in his summer chamber; that is, was easing nature; and, as the eastern people wore long and loose garments, when they sat down on such an occasion, their feet were covered with them; or they purposely gathered them about their feet to cover them, and so this became a modest expression for this work of nature, see 1 Samuel 24:3; though some think that in that place, and also in this, is meant lying down to sleep; and that Eglon's servants supposed that he had laid himself down on his couch in his summer chamber to take sleep, when it was usual to cover the feet with long garments, to hide those parts of nature which otherwise might be exposed; and it must be owned that this seems more agreeable to a summer parlour than the former, and better accounts for the servants waiting so long as they did; and Josephus (g) is express for it, that his servants thought he had fallen asleep. Indeed, the Jews in later times used the phrase in the first sense (h), which seems to be taken from hence.

(f) Ebr. Concord. part. p. 47. No. 237. (g) Ut supra. (Antiqu. l. 5. c. 4. sect. 2.) (h) Misn. Yoma, c. 3. sect. 2.

When the servants of Eglon came (to enter in to their lord) after Ehud's departure and saw the door of the upper room bolted, they thought "surely (אך, lit. only, nothing but) he covers his feet" (a euphemism for performing the necessities of nature; cf. 1 Samuel 24:3), and waited to shaming (cf. 2 King dg 2:17; Judges 8:11), i.e., till they were ashamed of their long waiting (see at Judges 5:28). At length they opened the door with the key, and found their lord lying dead upon the floor.

Ehud's conduct must be judged according to the spirit of those times, when it was thought allowable to adopt any means of destroying the enemy of one's nation. The treacherous assassination of a hostile king is not to be regarded as an act of the Spirit of God, and therefore is not set before us as an example to be imitated. Although Jehovah raised up Ehud as a deliverer to His people when oppressed by Eglon, it is not stated (and this ought particularly to be observed) that the Spirit of Jehovah came upon Ehud, and still less that Ehud assassinated the hostile king under the impulse of that Spirit. Ehud proved himself to have been raised up by the Lord as the deliverer of Israel, simply by the fact that he actually delivered his people from the bondage of the Moabites, and it by no means follows that the means which he selected were either commanded or approved by Jehovah.

When he was gone out, his servants came; and when they saw that, behold, the doors of the parlor were locked, they said, Surely he covereth his feet in his summer chamber.

3:24 Covereth his feet - This phrase is used only here, and 1Sam 24:3. A late judicious interpreter expounds it, of composing himself to take a little sleep, as was very usual to do in the day - time in those hot countries. And when they did so in cool places, such as this summer parlour unquestionably was, they used to cover their feet. And this may seem to be the more probable, both because the summer parlour was proper for this use, and because this was a more likely reason of their long waiting at his door, lest they should disturb his repose. And this sense best agrees with Saul's case in the cave, when being asleep, David could more securely cut off the lap of his garment.

covereth...: or, doeth his easement

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.
