He hath also stablished them forever and ever - He has made them firm, stable, enduring. That they may be eternal is possible; that they will not be, no one can prove. Matter, when created, has no necessary tendency to decay or annihilation; and the universe - the stars, and suns, and systems - which have endured so many million of ages may continue to exist any number of million of ages to come. Of course, however, all this is dependent on the will of God. On the meaning of this passage, compare Psalms 119:90, note; Psalms 72:5, note; Psalms 89:2, note; Psalms 89:36-37, note. See also 2 Peter 3:7, note; 2 Peter 3:10, note; 2 Peter 3:13, note.
He hath made a decree which shall not pass - He has given a law or statute which they cannot pass. The word rendered decree here seems to be used in the sense of limit or bound; and the idea is, that he has bound them by a fixed law; he has established laws which they are compelled to observe. The fact is, in regard to them, that he has established great laws - as the law of gravitation - by which they are held from flying off; he has marked out orbits in which they move; he has so bound them that they perform their revolutions with unerring accuracy in the very path which he has prescribed. So accurate are their movements that they can be predicted with exact precision; and so uniform, that any succession of ages does not vary or affect them.
