Genesis 42:6, 23, 27

Now Joseph was governor over the land. He was the one who sold to all the people of the land. And Joseph’s brothers came and bowed themselves before him with their faces to the ground.

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

And as one of them opened his sack to give his donkey fodder at the lodging place, he saw his money in the mouth of his sack.
