Genesis 46:8

“And these [are] the names of the children of Israel which came into Egypt, etc.] Not meaning precisely Jacob’s seed and offspring, but the body of the people of Israel, as they were when they went into Egypt, including Jacob himself: Jacob and his sons; for he went with them to Egypt, and was the head and principal of them: Reuben, Jacob’s firstborn; (see <012932>Genesis 29:32).”

“all the souls of the house of Jacob, which came into Egypt, were threescore and ten--Strictly speaking, there were only sixty-six went to Egypt; but to these add Joseph and his two sons, and Jacob the head of the clan, and the whole number amounts to seventy. In the speech of Stephen (Act 7:14) the number is stated to be seventy-five; but as that estimate includes five sons of Ephraim and Manasseh (Ch1 7:14-20), born in Egypt, the two accounts coincide.”
