What is Dr. Jekyll’s explanation of the will?

Two weeks later, Dr. Jekyll is holding a dinner party at which Mr. Utterson is a guest. After the guests leave, Utterson confronts Jekyll over the matter of his will and tells him that he has been learning about Mr. Hyde. Jekyll becomes upset when he hears of this and tells Utterson to drop the subject. Utterson urges Hyde to confide in him, but again Jekyll tells Utterson to leave the subject alone and assures him that he can be rid of Mr. Hyde at any point. As Mr. Utterson gets up to leave, Jekyll tells him that he does have a great interest in "poor Hyde" and apologizes for his rude behavior, but begs him to make sure that he takes care of Hyde when Jekyll is no longer there.
