John Gill Commentary Mark 11:6

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

And they said unto them The very express words,

even as Jesus had commanded : not that these were the words they said, but "the Lord has need of him": upon which they said no more, were satisfied and contented, that they should untie the colt, and take it with them:

and they let them go ; and the colt with them, very freely; (See Gill on Matthew 21:6).
