For the bed is shorter ... - This is evidently a proverbial saying, and means that they would find all their places of defense insufficient to secure them. They seek repose and security - as a man lies down to rest at night. But they find neither. His bed furnishes no rest; his scanty covering furnishes no security from the chills of the night. So it would be with those who sought protection in idols, in the promises of false prophets, and in the aid which might be obtained from Egypt. So it is with sinners. Their vain refuges shall not shield them. The bed on which they seek rest shall give them no repose; the covering with which they seek to clothe themselves shall not defend them from the wrath of God.

For the bed is shorter - A mashal or proverbial saying, the meaning of which is, that they will find all means of defense and protection insufficient to secure them, and cover them from the evils coming upon them. מסך massek, Isaiah 22:8, the covering, is used for the outworks of defense, the barrier of the country; and here, in the allegorical sense, it means much the same thing. Their beds were only mattresses laid on the floor; and the coverlet a sheet, or in the winter a carpet, laid over it, in which the person wrapped himself. For כהתכנס kehithcannes, it ought probably to be מהתכנס mehithcannes. Houbigant, Secker.

For the bed is shorter than that a man can stretch himself on it,.... When a bed is short, a man cannot lie at his full length, and at ease:

and the covering narrower than that he can wrap himself in it; when the bedclothes are narrow a man cannot cover himself with them, so as to be warm and comfortable. These proverbial expressions are interpreted by Kimchi of Jerusalem, when besieged by the Assyrian army, when the inhabitants of it were much straitened, distressed, and made uncomfortable; perhaps it may be better understood of the same city when besieged by the Romans, to which the Jews flocked from all parts, in such numbers, for shelter, that there was not room enough for them, at least not provision, and which was the cause of that great distress and miserable condition they were reduced to: in general, the design of the words may be to show that all refuges and shelters, all means made use of for safety and protection, by which they endeavoured to cover and secure themselves, would be insufficient; and particularly such that laid themselves at ease on the bed of their own righteousness, not submitting to Christ and his righteousness, and covered themselves with the rags of their own doings, and not with the garments of his salvation, would find themselves in a very uncomfortable and unsafe state.

For the bed is {z} shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it.

(z) Your affliction will be so sore, that you are not able to endure it.

28:20 For - For those lying refuges, to which you trust, will not be able to give you that protection, which you expect from them; no more than a man can stretch himself upon a bed that is too short for him.

20. Proverbial, for they shall find all their sources of confidence fail them; all shall be hopeless perplexity in their affairs.

28:16-22 Here is a promise of Christ, as the only foundation of hope for escaping the wrath to come. This foundation was laid in Zion, in the eternal counsels of God. This foundation is a stone, firm and able to support his church. It is a tried stone, a chosen stone, approved of God, and never failed any who made trial of it. A corner stone, binding together the whole building, and bearing the whole weight; precious in the sight of the Lord, and of every believer; a sure foundation on which to build. And he who in any age or nation shall believe this testimony, and rest all his hopes, and his never-dying soul on this foundation, shall never be confounded. The right effect of faith in Christ is, to quiet and calm the soul, till events shall be timed by Him, who has all times in his own hand and power. Whatever men trust to for justification, except the righteousness of Christ; or for wisdom, strength, and holiness, except the influences of the Holy Ghost; or for happiness, except the favour of God; that protection in which they thought to shelter themselves, will prove not enough to answer the intention. Those who rest in a righteousness of their own, will have deceived themselves: the bed is too short, the covering too narrow. God will be glorified in the fulfilling of his counsels. If those that profess to be members of God's church, make themselves like Philistines and Canaanites, they must expect to be dealt with as such. Then dare not to ridicule the reproofs of God's word, or the approaches of judgements.
