'Foal' in the Bible

“Tying his foal to the [strong] vineAnd his donkey’s colt to the choice vine,He washes his clothing in wine [because the grapevine produces abundantly],And his robes in the blood of grapes.

Rejoice greatly, O Daughter of Zion!Shout aloud, O Daughter of Jerusalem!Behold, your King (Messianic King) is coming to you;He is righteous and endowed with salvation,Humble and unassuming [in submission to the will of the Father] and riding on a donkey,Upon a colt, the foal of a donkey.

“Tell the daughter of Zion (the people of Jerusalem),‘Behold, your King is coming to you,Gentle and mounted on a donkey,Even on a colt, the foal of a beast of burden.’”
