But doubtless, when the Scripture mentions Jacob's entrance into Egypt with seventy-five souls, it does not mean one day, or one year, but that whole time as long as Joseph lived, who was the cause of his entrance. For the same Scripture speaks thus of Joseph: "And Joseph dwelt in Egypt, he and his brethren, and all his father's house: and Joseph lived 110 years, and saw Ephraim's children of the third generation."  That is, his great-grandson, the third from Ephraim; for the third generation means son, grandson, great-grandson. Then it is added, "The children also of Machir, the son of Manasseh, were born upon Joseph's knees."  And this is that grandson of Manasseh, and great-grandson of Joseph. But the plural number is employed according to scriptural usage; for the one daughter of Jacob is spoken of as daughters, just as in the usage of the Latin tongue liberi is used in the plural for children even when there is only one. Now, when Joseph's own happiness is proclaimed, because he could see his great-grandchildren, it is by no means to be thought they already existed in the thirty-ninth year of their great-grandsire Joseph, when his father Jacob came to him in Egypt. But those who diligently look into these things will the less easily be mistaken, because it is written, "These are the names of the sons of Israel who entered into Egypt along with Jacob their father."  For this means that the seventy-five are reckoned along with him, not that they were all with him when he entered Egypt; for, as I have said, the whole period during which Joseph, who occasioned his entrance, lived, is held to be the time of that entrance.
 Augustin here follows the Septuagint, which at Genesis 46:20 adds these names to those of Manasseh and Ephraim, and at ver. 27 gives the whole number as seventy-five. 1 Genesis 50:22, 23.  Genesis 50:22, 23.  Genesis 50:23.  Genesis 46:8.
