The sons of Naphtali were Jahzeel, Guni, Jezer, and Shillem.
These were the descendants of Bilhah, whom Laban gave to his daughter Rachel. She gave birth to these sons for Jacob. The total was 7.
The total number of Jacob's direct descendants who went with him to Egypt was 66. This didn't include the wives of Jacob's sons.
Joseph had two sons who were born in Egypt. The grand total of people in Jacob's household who went to Egypt was 70.
Israel sent Judah ahead of him to Joseph to get directions to Goshen. When Israel's family arrived in the region of Goshen,
Joseph prepared his chariot and went to meet his father Israel. As soon as he saw his father, he threw his arms around him and cried on his shoulder a long time.
Israel said to Joseph, "Now that I've seen for myself that you're still alive, I'm ready to die."
Then Joseph said to his brothers and his father's family, "I'm going to Pharaoh to tell him, 'My brothers and my father's family, who were in Canaan, have come to me.
The men are shepherds. They take care of livestock. They've brought their flocks and herds and everything they own.'
Now, when Pharaoh calls for you and asks, 'What kind of work do you do?'
you must answer, 'We have taken care of herds all our lives, as our ancestors have done.' [You must say this] so that you may live in the region of Goshen, because all shepherds are disgusting to Egyptians."
