For ever, O Lord, thy word is setled in heaven] Because none should esteem Gods word, according to the changes of things in this world, he sheweth, that it abideth in heaven, and so abideth immutable: or, the permanency of it, is seen in the continuance of the heavens: so of the earth, vers. 90. and so vers. 91. They continue, that is, heaven and earth, for they are thy servants.
