In God announced that God would "put the plague of leprosy in a house of the land of your possession." Rabbi Hiyya asked: Was it then a piece of good news that plagues were to come upon them? Rabbi Simeon ben Yohai answered that when the Canaanites heard that the Israelites were approaching, they hid their valuables in their houses. But God promised the Israelites' forbearers that God would bring the Israelites into a land full of good things, including (in the words of ) "houses full of all good things." So God brought plagues upon a house of one of the Israelites so that when he would pull it down, he would find a treasure.
