'Colt' in the Bible

saying, Go into the village over against you, in which ye will find, on entering it, a colt tied up, on which no child of man ever sat at any time: loose it and lead it here.

And as they were loosing the colt, its masters said to them, Why loose ye the colt?

And they led it to Jesus; and having cast their own garments on the colt, they put Jesus on it.
