A.T. Robertson Commentary Luke 19:30

"saying, Go your way into the village over against [you]; in which as ye enter ye shall find a colt tied, whereon no man ever yet sat: loose him, and bring him." — Luke 19:30 (ASV)

Whereon no man ever yet sat (εφ' ον ουδεις πωποτε ανθρωπων εκαθισεν). Plummer holds that this fact indicated to the disciples a royal progress into the city of a piece with the Virgin Birth of Jesus and the burial in a new tomb.
