When they came near Jerusalem and had reached Bethphage on the Mount of Olives, Jesus sent two disciples ahead of him. He said to them, “Go into the village ahead of you. You will find a donkey tied there and a colt with it. Untie them, and bring them to me. If anyone says anything to you, tell him that the Lord needs them. That person will send them at once.”
This happened so that what the prophet had said came true:

“Tell the people of Zion,
    ‘Your king is coming to you.
        He’s gentle,
            riding on a donkey,
                on a colt, a young pack animal.’”
