This saying is already said by Celestina in the dialogue with Calisto of act six. To get what you want you have to fight hard and be patient. The saying alludes to the siege of Zamora de Sancho II against his sister Urraca. And indeed he could not take Zamora neither in an hour nor in seven months, which is what lasted the siege in 1072, because it ended with the death of King Sancho II near the walls next to the gate that until recently called the Zamorans the portof treason and now empi they call the porch of haired Dolfos and other release portillo.
