Mark 14:12-15

On the first day [of the festival] of Unleavened Bread, when [as was customary] they sacrificed the Passover lamb, His disciples asked Him, “Where do You want us to go and prepare for You to eat the Passover?” [Matt 26:17-19; Luke 22:7-13] And He sent two of His disciples, saying to them, “Go into the city, and a man carrying a jar of water will meet you; follow him; and say to the owner of the house he enters, ‘The Teacher asks, “Where is My guest room in which I may eat the Passover with My disciples?” ’ He will show you a large upstairs room, furnished and ready [with carpets and dining couches]; prepare [the supper] for us there.”
