Chapter 46 begins with Israel and his whole family headed for Egypt. It doesn't say he was apprehensive of the move but God coming to him in a vision and reassuring him to go and saying He would go with him implies it. He was probably hesitant since God had told Isaac not to go to Egypt during a previous famine.
Israel reuniting with his son Joesph obviously was a very emotional moment. He had thought his son was dead for years now he gets to embrace him. God gets just as emotional with such joy when we turn from our dead lives and accept Jesus to begin living eternal lives with Him!!
The famine was so bad people spent all their money, traded all their livestock and eventually even sold their land and freedom. Some may say Joesph was being harsh to them but he was keeping the peace and giving them food. They didn't seem upset in 47:25 they say "You have saved our lives." They seem grateful for the fact he didn't let them starve to death.
After living in Egypt seventeen years, Jacob was close to death and had Joesph swear to bury him where his fathers were back in the land of Canaan. Joesph agreed to do so.
