Jacob traveled to Egypt in a cart with all his family, his servants and animals.
The cart was supplied by his son Joseph, who now was second to the Pharaoh of Egypt.
If Joseph had not been sold into slavery all those many years ago God could not have used Him to Save his family.
Jacob was promised by God - You will go in few and come out many. To see if this happened look up the life of Moses.
Jacob Goes to Egypt46So Israel set out with all that was his, and when he reached Beersheba, he offered sacrifices to the God of his father Isaac.
2 And God spoke to Israel in a vision at night and said, "Jacob! Jacob!"
"Here I am," he replied.
3 "I am God, the God of your father," he said. "Do not be afraid to go down to Egypt, for I will make you into a great nation there. 4 I will go down to Egypt with you, and I will surely bring you back again. And Joseph's own hand will close your eyes."
5 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. 6 They also took with
them their livestock and the possessions they had acquired in Canaan,
and Jacob and all his offspring went to Egypt. 7 He took
with him to Egypt his sons and grandsons and his daughters and
granddaughters—all his offspring.
