He shall enter into peace. Not merely into "stillness" or "silence" (Psalms 115:17), but into "peace," or, as the word might be rendered (Cheyne), "a state of peace." There is, no doubt, primarily, "a contrast to the awful troubles which the survivors will have to encounter" (Hengstenberg); but perhaps this contrast is not all that is meant.
The "peace" is positive rather than negative, or it would scarcely be a consolation to any one. They shall rest in their beds; or, upon their beds. This expression seems to imply a consciousness of rest, and so a certain enjoyment of it.
Each one walking in his uprightness; rather, whosoever hath walked uprightly, or in a straight path (see Proverbs 4:25-27). The phrase is an equivalent for "the righteous" of Isaiah 57:1, and refers to the life on earth of those who have gone down into silence, not to their life after they have reached the silent shore.
Of that life the evangelical prophet is not commissioned to give us any information.
