A.T. Robertson Commentary Matthew 21:2

"saying unto them, Go into the village that is over against you, and straightway ye shall find an ass tied, and a colt with her: loose [them], and bring [them] unto me." — Matthew 21:2 (ASV)

Into the village that is over against you (εις την κωμην την κατεναντ υμων). Another use of εις. If it means "into" as translated, it could be Bethany right across the valley and this is probably the idea.

And a colt with her (κα πωλον μετ' αυτης). The young of any animal. Here to come with the mother and the more readily so.
