雅各就從別是巴起行。以色列的兒子們使他們的父親雅各和他們的妻子、兒女都坐在法老為雅各送來的車上。他們又帶著迦南地所得的牲畜、貨財來到埃及。雅各和他的一切子孫都一同來了。(創46:5-6) 創 46:7-25 (略)

Then Jacob left Beersheba, and Israel’s sons took their father Jacob and their children and their wives in the carts that Pharaoh had sent to transport him. They also took with them their livestock and the possessions they had acquired in Canaan, and Jacob and all his offspring went to Egypt.

那與雅各同到埃及的，除了他兒婦之外，凡從他所生的，共有六十六人。還有約瑟在埃及所生的兩個兒子。雅各家來到埃及的共有七十人。(創26:26-27)

All those who went to Egypt with Jacob-those who were his direct descendants, not counting his sons’ wives-numbered sixty-six persons. With the two sons who had been born to Joseph in Egypt, the members of Jacob’s family, which went to Egypt, were seventy in all.

雅各的兒孫包括出自利亞的兒孫33人(46:15)，出自悉帕的兒孫16人(46:18)，出自拉結的兒孫14人(46:22)，出自辟拉的兒孫7人(46:25)，共有70人。其中猶大的兒子珥與俄南死在迦南地(46:12)，約瑟和他的兩個兒子瑪拿西、以法蓮已在埃及，所以經上說：「那與雅各同到埃及的，除了他兒婦之外，凡從他生的(包括女兒底拿，她沒有列在利亞的兒孫33人中)，共有66人(66=70-2-3+1)。」(創46:27)(出1:5)(申10:22)。

到了新約的使徒行傳，司提反說：「約瑟就打發弟兄請父親雅各和全家75個人都來。」(徒7:14)這全家「75」(75=70-2+7)人的算法，是從70人中減去雅各和約瑟二人(因雅各是父親不與兒孫同列，而約瑟的名份被他的兩個兒子取代了)，再加上後來約瑟的兒子瑪拿西所生的三個兒子和以法蓮所生的四個兒子(代上7:14-23)，這7人也都算是雅各的兒孫。
