Expositor's Bible Commentary Commentary Mark 11:6

"And they said unto them even as Jesus had said: and they let them go." — Mark 11:6 (ASV)

The disciples found the colt as Jesus had told them and carried out his orders to the letter. The people (the owners? see Lk 19:33) did not object to the disciples’ taking the colt because apparently they knew Jesus and recognized his authority.
