Zadkiel or Hesediel (Heb. צדקיאל Tzadqiel, "Righteousness of God") is the archangel of freedom, benevolence, mercy, and the Patron Angel of all who forgive. Also known as Sachiel, Zedekiel, Zadakiel, Tzadkiel, Zedekul and Hesediel.
In rabbinic writings Zadkiel belongs to the order of Hashmallim (equated with the Dominations or Dominions), and considered by some sources to be chief of that order (others sources name Hashmal or Zacharael). In Maseket Azilut Zadkiel/Hesediel is listed as co-chief with Gabriel of the order of Shinanim. As an angel of mercy, some texts claim that Zadkiel is the unnamed Biblical Angel of the Lord who holds back Abraham to prevent the patriarch from sacrificing his son, and because of this is usually shown holding a dagger. Other texts cite Michael or Tadhiel or some other angel as the angel intended, while others interpret the Angel of the Lord as a theophany.
