Mark 11:3-6
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.
11:5 Some people standing there said to them, “What are you doing, untying that colt?”
11:6 They replied as Jesus had told them, and the bystanders let them go.
