How many generations of Joseph's descendants did Joseph live to see?
Joseph lived to see his descendants to the third generation, as Scripture records he saw Ephraim's children of the third generation and the children of Masher, son of Manasseh, who were brought up upon Joseph's knees. This indicates three generations of descendants.
Les explains that Joseph lived 110 years and saw Ephraim's children of the third generation, along with the children of Masher, the son of Manasseh, who were brought up upon Joseph's knees. This means Joseph lived to see three generations of his descendants. The context also records Joseph's final words to his brethren, his oath that God would surely visit Israel and they should carry his bones back to Canaan, and his death at 110, after which he was embalmed and put in a coffin in Egypt. Les notes that Genesis ends with a coffin, but God's program continues, for God buries His servants but never His program.
