Mark 11:6

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 hath 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).
