And when they drew near to Jerusalem, to Beth’phage and Bethany, at the Mount of Olives, he sent two of his disciples, and said to them, “Go into the village opposite you, and immediately as you enter it you will find a colt tied, on which no one has ever sat; untie it and bring it. If any one says to you, ‘Why are you doing this?’ say, ‘The Lord has need of it and will send it back here immediately.'” And they went away, and found a colt tied at the door out in the open street; and they untied it. And those who stood there said to them, “What are you doing, untying the colt?” And they told them what Jesus had said; and they let them go.
–Mark 11:1-6
