Those passages were never meant to be taken literal... they would laugh at you.
They are allegorical...  always have been... always will be.
		
		
	 
Matthew 21:1 When they had approached Jerusalem and had come to Bethphage, at the Mount of Olives, then Jesus sent two disciples, 2 saying to them, "Go into the village opposite you, and immediately you will find a donkey tied there and a colt with her; untie them and bring them to Me. 3 "If anyone says anything to you, you shall say, 'The Lord has need of them,' and immediately he will send them."…4 
This took place to fulfill what was spoken through the prophet:…"Say to Daughter Zion, 'See, your king comes to you, gentle and riding on a donkey, and on a colt, the foal of a donkey.'"
Isaiah 62:11
The LORD has made proclamation to the ends of the earth: "Say to Daughter Zion, 'See, your Savior comes! See, his reward is with him, and his recompense accompanies him.'"
Zechariah 9:9
Rejoice greatly, Daughter Zion! Shout, Daughter Jerusalem! See, your king comes to you, righteous and victorious, lowly and riding on a donkey, on a colt, the foal of a donkey.
Genesis 49:11
He will tether his donkey to a vine, his colt to the choicest branch; he will wash his garments in wine, his robes in the blood of grapes.
All looks literal to me, even says it is in Matthew and its cited.
