Chasidut zu Bereschit 45:26

Genesis 45,26. “when he saw the carriages that Joseph ‎had sent, etc.” Joseph had hinted to Yaakov that he should ‎not be concerned about his family going into exile, as what was ‎occurring now was a forerunner of the eventual redemption from ‎exile. Temporary hardship, such as their having to leave the Holy ‎Land now, would result in much greater good in the end. Both ‎the word ‎עגלה‎, carriage, which is a chair or couch on circular ‎wheels, i.e. ‎עיגול‎, circle, and the word ‎סיבה‎, the cause of Yaakov ‎been transported to Egypt on wheels into “exile” is related to this ‎revolving nature of fate, ‎סבב‎, spinning, revolving. Joseph wished ‎to indicate to his father that temporary residence of his family in ‎Egypt would result subsequently in his descendants inheriting ‎the whole land of Israel.‎
