Mark 11:2-4
11:2 and said to them, “Go to the village ahead of you. As soon as you enter it, you will find a colt tied there that has never been ridden. Untie it and bring it here.
11:3 If anyone says to you, ‘Why are you doing this?’ say, ‘The Lord needs it and will send it back here soon.’”
11:4 So they went and found a colt tied at a door, outside in the street, and untied it.
