The word "Now" is used here to mark a break in the story. The author stops telling about Abigail going to David and tells about what David had said sometime before Abigail went to him.
This can be stated positively and in active form. Alternate translation: "he still has everything that was his" (See: [[rc://en/ta/man/jit/figs-litotes]] and [[rc://en/ta/man/jit/figs-activepassive]])
