• Canons Bearing a Torch Before the Pentateuch — Cited as example of a precept that may bind under venial rather than mortal sin

  "You shall not sow your field with diverse seed"

Chapter I (The Six Days of Creation)

• Verse 24: Let the Earth Bring Forth the Living Creature — Hybridization is contrary to nature and adulterous, forbidden to the Jews
