Adapun Yusuf, dialah penguasa atas negeri itu; dialah yang menjual gandum kepada seluruh rakyat negeri itu. Maka datanglah saudara-saudara Yusuf, lalu sujud kepadanya dengan muka sampai ke tanah.
Rashi
וישתחוו לו אפים means THEY PROSTRATED THEMSELVES ON THEIR FACES— Similarly wherever various forms of this verb (שחה) in the Hithpael occur it implies stretching out the hands and feet when a person casts himself on the ground in the act of prostration (Megillah 22b).
Alshekh
He acted like a stranger. The brothers committed five sins: 1) hating him; 2) plotting to kill him; 3) casting him into the pit; 4) selling him; and 5) causing their father anguish. To save them from punishment Yoseif afflicted them in five ways: 1) speaking to them harshly; 2) accusing them of spying; 3) casting them into prison; 4) frightening them with the return of the money; and 5) accusing them of stealing his goblet.

Ed.] He collected the money from all the customers. The reason that he did this was so that when, as he expected, his brothers would show up, he would immediately be aware of this.
