Storytelling becomes more prominent in Persian tafsirs. They are known especially for their colorful and dramatic depiction of scenes in the narratives. It is often described as "lively," which can be seen in Joseph's interactions with his brothers. Another example of Persian expansion of the language is when the brother's realize that Joseph is going to keep Benjamin in Egypt. One of the brothers, often Rueben, is said to have threatened Joseph that he would yell so loudly that every pregnant woman would immediately deliver her child.
