Now these are the names. Literally, "And these are the names." Compare Genesis 46:8, where the phrase used is the same. We have here the first example of that almost universal practice of fife writers of the Historical Scriptures to connect book with book in the closest possible way by the simple copulative "and."
(Compare Joshua 1:1, 1:1, Ruth, Samuel, Kings, Ezra, Nehemiah, and Esther.) This practice, so unlike that of secular writers, can only be explained by the instinctive feeling of all, that they were contributors to a single book, each later writer a continuator of the narrative placed on record by his predecessor.
In the Pentateuch, if we admit a single author, the initial vau will be less remarkable, since it will merely serve to join together the different sections of a single treatise. Which came into Egypt.
