What does Genesis 50:24 mean?
The once-hated younger brother, sold as a slave (Genesis 37:26–28) has spent the last eighty years as a powerful ruler in Egypt (Genesis 41:44–46; 50:22). He has lived a good, long life, and at the end his focus is the same as that of his father Jacob. Egypt has been good to Joseph and to his family (Genesis 47:5–6), but the people of God are not meant to stay in Egypt forever.Prophetically, Joseph tells his gathered family that God will visit them at some point. The Lord will keep the promises made to Abraham, Isaac, and Jacob (Genesis 17:5–8). That means bringing the people of Israel (Genesis 35:10–11) out of Egypt and back to Canaan to take ownership of it.
The mention of Joseph's brothers here may refer to their sons or the representative heads of their families. It's unknown how many of the original twelve were still living by the time Joseph reached 110 years of age. Ten of his brothers were older than him. Only Benjamin was younger. Most likely, at least some of the older brothers have already passed away.
