Genesis 42:6, 23, 27

Now Joseph was the ruler over the land; he was the one who sold to all the people of the land. And Joseph’s brothers came and bowed down to him with their faces to the ground.

They did not know, however, that Joseph understood, for there was an interpreter between them.

As one of them opened his sack to give his donkey fodder at the lodging place, he saw his money; and behold, it was in the mouth of his sack.
