Zechariah 9:9 (Old testament prophecy.) "Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass."

Matthew 21:2-9 (Fulfilled in new testament.)

"Saying unto them, Go into the village over against you, and straightway ye shall find an ass tied, and a colt with her: loose them, and bring them unto me.

And if any man say ought unto you, ye shall say, The Lord hath need of them; and straightway he will send them.

All this was done, that it might be fulfilled which was spoken by the prophet, saying,

Tell ye the daughter of Sion, Behold, thy King cometh unto thee, meek, and sitting upon an ass, and a colt the foal of an ass.

And the disciples went, and did as Jesus commanded them,

And brought the ass, and the colt, and put on them their clothes, and they set him thereon.

And a very great multitude spread their garments in the way; others cut down branches from the trees, and strawed them in the way.

And the multitudes that went before, and that followed, cried, saying, Hosanna to the son of David: Blessed is he that cometh in the name of the Lord; Hosanna in the highest."
