Because Reuben slept with his father’s concubine, he lost the birthright to Joseph, which would go to his two sons, which Jacob/Israel now adopts. Instead of there being a tribe of Joseph, there will instead be two half-tribes of Ephraim and Manasseh (for now Joseph will receive a double portion…possibly referring to the Hebrew for Shechem, after what happened in chapter 34). For what Levi and Simeon did in chapter 34, they would not receive land allotments…Simeon would eventually be absorbed into Judah, and Levi would be set apart for priestly duty and given 48 towns scattered throughout Israel. As Jacob, the younger brother, received the blessing and preferred Rachel, the younger daughter, he now shows preference to the younger son, Ephraim.
Job: So, Job says “Behold, I am insignificant ; what can I reply to You? I lay my hand on my mouth. Once I have spoken, and I will not answer ; Even twice, and I will add nothing more” But God doesn’t let up. It’s as if he only asked Job a question and let him stutter out the answer as ‘part’ of His long reply.
