Translation:

62. And (Joseph) told his servants to put their stock in trade (with which they had bartered) into their saddlebags so they should know it only when they returned to their people in order that they might come back.

Notes (Tafseer)

1722. Bidha'at: stock in trade; capital with which business is carried on; money-when it is used as capital for trade. It is better here to suppose that they were bartering goods for grain. Cf. xii. 19.

1723. It was most important for Joseph's plan that they should come back. If they came back at all, they could not come without Benjamin after what he had told them. As an additional incentive to their coming back, he returns the price of the grain in such a way that they should find it in their saddle-bags when they reach home.
