"Gad: "Hear now, my children, the words of truth, that ye may practice justice and the whole law of the Most High, and permit yourselves not to be tempted by the spirit of hatred. Evil is hatred, for it is the constant companion of deception, it always contradicts the truth. A little thing it magnifies into a great thing, light it takes for darkness, the sweet it calls bitter, and it teaches slander, enkindles anger, brings on war and violence, and fills the heart with devilish poison. I tell you my own experience, my children, that ye may drive hatred out of your hearts, and cleave to the love of the Lord. Righteousness banishes hatred, and humility kills it, for he that fears to give umbrage to the Lord, desires not to do wrong even in his thoughts. This is what I recognized at the last, after I had done penance on account of Joseph, for true atonement, pleasing to God, enlightens the eyes, illumines the soul with knowledge, and creates a counsel of salvation. My penance came in consequence of a sickness of the liver that God inflicted upon me. Without the prayers of my father Jacob, my spirit would have departed from me, for through the organ wherewith man transgresses, he is punished. As my liver had felt no mercy for Joseph, unmerciful suffering was caused unto me by my liver. My judgment lasted eleven months, as long as my enmity toward Joseph."
