According to the Midrash, the Angel of Death was created by God in the first day of the creation. His house is in Heaven.He has twelve wings."Over all people have I surrendered thee the power," said God to the Angel of Death, "only not over this one which has received freedom from death through the Law".It said that the angel of death is full of eyes. In the time of the death, he stands over the dying one, and waiting for the man to see him. When the dying finally sees him, he drops a gall to the dying's mouth and that is what kills him finally The expression "to taste of death" originated in the idea that death was caused by a drop of gall.
