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. Matthew 21:5-7
And they brought the colt to Jesus, and cast their garments on him; and he sat upon him. Mark 11:7
And they brought him to Jesus: and they cast their garments upon the colt, and they set Jesus thereon. Luke 19:35
And Jesus, when he had found a young ass, sat thereon. John 12:14
Note from The New Oxford Annotated Bible for Matthew 21:5: "The Hebrew text refers not to two animals but to one. The reference to the two in v.7 may have arisen through misunderstanding of the form of Hebrw poetic expression in Zech 9.9."
