Adam Clarke on Job 29:2

O that I were as in months past - Job seems here to make an apology for his complaints, by taking a view of his former prosperity, which was very great, but was now entirely at an end. He shows that it was not removed because of any bad use he had made of it; and describes how he behaved himself before God and man, and how much, for justice, benevolence, and mercy, he was esteemed and honored by the wise and good.

Preserved me - Kept, guarded, and watched over me.
