Manasseh was the first-born child of Joseph who was put as a “second son” by Jacob. Joseph in naming Manasseh and Ephraim demonstrates that he was perfectly happy with his new life and had no intention of going back. (Genesis 41:51+52) He had the power to send a message back to his family but he did not.
I wonder how these two acted around the rest of the family? They were children of the ruler of the country they lived in and because of being Egyptian possibly had more privileges. From Genesis 48:1 I would wonder if Joseph even allowed them to live around his brothers? Joseph may have had them marry within the family but Manasseh definitely owned slaves and even had a foreign concubine.
1 Chronicles 7:14+15 talks about Manasseh’s two notable descendents: Gilead and Zelophehad. In Numbers 36 Zelophehad dies in the exodus and leaves only daughters, these girls stand up for themselves and their father’s lineage. The daughters go to Moses and plead their case before God; this leads to a new decree to acknowledge women as heirs. It may not sound like much but that was groundbreaking territory when women were viewed much of the time as second-class people or property. The other descendent was Gilead who was to lend his name to the area of the east bank of the Jordan River that was the inheritance of the tribes of Manasseh, Rueben and Gad. This is a contrast to Zelophehad’s daughters; Gilead comes from an Aramean concubine and a group of people who were not Israelites (Huppites and Shuppites). Just like Bilhah and Zilpah this concubine was a slave that Manasseh used and was so elevated to a slightly better status in the household. You get the feeling that the children were valued but not the mother (Sarah and Hagar).
In 1 Chronicles 5: 18 -26 it gives two contrasting stories; one of faith and trust in God and the other of unfaithfulness to Him. In verse 20 the East Bank tribes cry out to God for help in the middle of a battle and are helped and overcome their enemies. In verse 25 it tells of the unfaithfulness that gets them taken away by Tiglath-Pileser.
Actually, Manasseh’s descendents were on par with the other tribes; they did their part in taking the Promise Land and showed up at all the right times and were active during the life time of Saul and David. Lo Debar is in the allotment of land given to Manasseh and it was this area that David went to when he ran from Absalom.
