Here the word "hope" is the reason for which a person can expect that what he desires will happen. Now that the spirit was gone, the girl's masters could not expect to earn money from the spirit's telling people things. Alternate translation: "their opportunity to make money was now gone" or "they could no longer expect to make money" (See: [[rc://en/ta/man/translate/figs-abstractnouns]])
It can be stated clearly why they no longer expected to make money. Alternate translation: "she could no longer earn money for them by telling fortunes" (See: [[rc://en/ta/man/translate/figs-explicit]])
