The Lord's Prayer for Thee, Forgive the Trespass of the Servants of the God of Thy Father

Joseph was buried in the cave of macpalah, which abraham bought with the field for a possession of the burying place of ephron before mamri. When joseph's brethren saw that their father was dead, they said, joseph will now hate us and will certainly pay back to us all the evil which we did unto him. And he comforted them and spake kindly unto them. So the the idea there is that there is no evil so evil that good cannot triumph over it.
