Genesis 50:24-25

24“Soon I will die,” Joseph told his brothers, “but God will surely come to help you and lead you out of this land of Egypt. He will bring you back to the land he solemnly promised to give to Abraham, to Isaac, and to Jacob.”

25Then Joseph made the sons of Israel swear an oath, and he said, “When God comes to help you and lead you back, you must take my bones with you.”
