How far through the Bible do the names Abraham, Isaac, and Jacob continue to appear?
Those three names—Abraham, Isaac, and Jacob—keep appearing all the way through Scripture, continuing well into the New Testament. They recur repeatedly from Genesis onward, tied to God's promise of the land sworn to the patriarchs, and they do not stop at the close of Genesis.
In the closing verses of Genesis 50, Joseph tells his brethren that God will surely visit them and bring them out of Egypt unto the land which He sware to Abraham, Isaac, and Jacob. Les points out that those three names just keep popping up all the way through Scripture, well into the New Testament. Joseph then took an oath of the children of Israel, saying God would surely visit them and that they should carry up his bones back to Canaan. Joseph died at 110 years old, having seen Ephraim's children of the third generation and the children of Machir, the son of Manasseh, brought up upon his knees. He was embalmed and put in a coffin in Egypt, and so ends the book of Genesis—the book of beginnings that starts with "in the beginning God created" yet ends with a coffin, death. Les adds the reminder, which he credits to other authors he has read, that God buries His servants but never His program: great men of God come and go, but God's program just keeps moving on.
