Reunion and Testing
Correction/Clarification: When I was comparing Benjamin to the other brothers and said that "all the other brothers were from Leah", that was not correct. Besides Benjamin and Joseph, Rachel did have two kids through her handmaid Bilhah: Dan and Naphtali. However, there is no indication in the text that 6 sons from Leah/Zilpah mistreated Dan and Naphtali. Bottom line, a close look at Genesis 37 shows that there is division only between Joseph and the rest of the brothers (no information is given about Benjamin who was young at the time). All the other brothers seemed unified together.
