Ibn Ezra
As the days of the tree that lives for a long time, as the Carob32Comp. Targ. Jonath.: כיומי אילן חייא, as the days of the tree of life; this refers, perhaps, likewise, to the carob tree, which is called the tree of life, on account of its longevity, its evergreen leaves, or its abundance of nutritious food. and similar trees.
Ibn Ezra
And mine elect shall outlive the work of their hands. Many works of man retain still their new appearance, while man has already become old, as e.g. a building, a book. The pronoun their refers to mine elect, the subject of the sentence.
