The Omnibenevolence of God

Does the Bible contain an unambiguous statement that God is All-Good? (Note: I am not questioning whether God is All-Good or not, nor how we can indirectly infer God is All-God. I am not asking whether the Bible contains God is All-Loving or All-Merciful or All-Powerful, but whether Bible explicitly mentions God is All-Good or a term that unequivocally means All-Good.) **ADDENDUM** (In response to people wondering why I am wondering what I am wondering.) In Islam there is this concept of *Most Beautiful and Perfect Names and Attributes of Allah.* (Obviously, all of them are from the Quran.) By itself, it is whole subject of endless research and commentary. Though God is not bounded by any number of perfect attributes, it is believed that 99 of them are mentioned in the Quran. I read that even though God is Perfectly Just, All-Just (or Absolute Just) is not a name mentioned in the Quran. (When I learned why, I was most amazed.) Then I realized that, to my understanding, there is no name that would correspond to All-Good, even though Allah *is* All Good. (And I have a theory why.) All of this made me curious: whether God is ever mentioned as All-Good in the Bible. I would guess not, this why I am asking here. Finally, the answer will help me with my own research and book.
