What does Genesis 37:28 mean?
Except for Reuben, who was not present (Genesis 37:22), Joseph's older brothers have agreed to sell him as a slave to the Ishmaelites (Genesis 25:23–27). In this verse, the specific group passing by are referred to "Midianite" traders. Scholars suggest that by this point in history, nomadic tribes in the region were referred to as "Ishmaelites," whether they were specifically descended from Hagar's son (Genesis 25:12) or not. This group of nomads were Midianites, descended from Abraham's concubine Keturah (Genesis 25:1–2).Joseph is lifted out the pit and handed over to the traders in exchange for 20 shekels of silver. Apparently, this was the going rate for a teenage slave at the time. Joseph's brothers profited from his sale. They assume they have seen the last of Joseph as he is hauled away to Egypt. Instead, God will use their cold-hearted actions to bring Joseph's dreams to reality in the most unexpected of ways (Genesis 42:6; 50:20).
