Psalms 89:2

I have said within myself. I have been assured in my own mind. Mercy shall be built up for ever: as thou hast laid a sure foundation of mercy to David's family, by that everlasting covenant which thou hast made and established with it; so I concluded that thou wouldst carry on the same project of mercy towards it; that thou wouldst build it up, and not destroy it. Thy faithfuless shalt thou establish in the very heavens: so the sense may be this. Thou sittest in the heavens, and there thou didst make this everlasting and unchangeable decree and covenant concerning David and his house, and from thence thou beholdest and orderest all the affairs of this lower world, and therefore, I doubt not, thou wilt so order these matters as to accomplish thine own counsel and word. But thee Hebrew words are by some others, and may very well be, translated thus, with (as the Hebrew prefix beth is oft rendered) the very heavens, i.e. as firmly and durably as the heavens themselves; as with the sun, in the Hebrew text, Psalms 72:5, is by most interpreters rendered, as long as the sun endureth, as our translation hath it. And so this phrase in the last branch of this verse answers to for ever in the former; as it is also in the foregoing verse, and so in Psalms 89:4; in both which verses for ever in the first clause is explained thus in the latter, to all generations.
