Zech 9:9, Mt 21:1-5, Jn 12:14-15
The Old Testament prophesied that a Savior who would save us would come to this earth. (Isa 62:11, Zechariah 9:9)
Isa 62:11 Behold, the Lord hath proclaimed unto the end of the world, Say ye to the daughter of Zion, Behold, thy salvation cometh; behold, his reward is with him, and his work before him.
Zechariah 9:9 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.
Jesus is the Christ who came to this earth as King and Savior as prophesied in the Old Testament. (Matthew 21:1-5, John 12:14-15)
Matthew 21:1 And when they drew nigh unto Jerusalem, and were come to Bethphage, unto the mount of Olives, then sent Jesus two disciples, 2 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. 3 And if any man say ought unto you, ye shall say, The Lord hath need of them; and straightway he will send them. 4 All this was done, that it might be fulfilled which was spoken by the prophet, saying, 5 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.
John 12:14 And Jesus, when he had found a young ass, sat thereon; as it is written, 15 Fear not, daughter of Sion: behold, thy King cometh, sitting on an ass's colt.
