A.T. Robertson Commentary Mark 11

Unto Bethphage and Bethany (εις Βηθφαγη κα Βηθανιαν). Both together as in Lu 19:29, though Mt 21:1 mentions only Bethphage. See discussion in Matthew for this and the Mount of Olives.

As ye enter (εισπορευομενο). So also Lu 19:30. Present middle participle.

Colt (πωλον). So Lu 19:30. Matthew 21:2 speaks of the ass (ονον) also.

Whereon no one ever yet sat (εφ' ον ουδεις ανθρωπων εκαθισεν). So Lu 19:30.

The Lord (ο Κυριος). So Matt. and Luke. See on Mt 21:3 for discussion of this word applied to Jesus by himself.

He will send him back (αποστελλε). Present indicative in futuristic sense. Matthew 21:3 has the future αποστελε.

A colt tied at the door without in the open street (πωλον δεδεμενον προς θυραν εξω επ του αμφοδου). A carefully drawn picture. The colt was outside the house in the street, but fastened (bound, perfect passive participle) to the door. "The better class of houses were built about an open court, from which a passage way under the house led to the street outside. It was at this outside opening to the street that the colt was tied" (Gould). The word αμφοδος (from αμφω, both, and οδος, road) is difficult. It apparently means road around a thing, a crooked street as most of them were (cf. Straight Street in Ac 9:11). It occurs only here in the N.T. besides D in Ac 19:28. It is very common in the papyri for vicus or "quarter."

And they loose him (κα λυουσιν αυτον). Dramatic present tense. Perhaps Peter was one of those sent this time as he was later (Luke 22:8). If so, that explains Mark's vivid details here.

Certain of those that stood there (τινες των εκε εστηκοτων). Perfect active participle, genitive plural. Bystanders. Luke 19:33 terms them "the owners thereof" (ο κυριο αυτου). The lords or masters of the colt. They make a natural protest.
