act 2 scene 5

Shylock informs Lancelot that he will have to judge for himself whether Bassanio is a better master. He then calls Jessica, hands her the keys to the house, and tells her that he must leave for dinner that evening. Lancelot tells Shylock that there will likely be a masque that night. At this news, Shylock orders Jessica to lock up the house and not look out the windows. He says, "Let not the sound of shallow fopp'ry enter / My sober house" (2.5.34-35).
