Palm Sunday

And after He had said these things, He was going on ahead, ascending to Jerusalem.
And it came about that when He approached Bethpage and Bethany, near the mount that is called Olivet, He sent two disciples, saying, "Go into the village opposite you, in which as you enter you will find a colt tied, on which no one yet has ever sate; untie it, and bring it here. And if anyone asks you, 'Why are you untying it?' thus shall you speak, 'The Lord has need of it.'"
And those who were sent went away and found it just as He had told them. And as they were untying the colt, its owners said to them, "Why are you untying the colt?"
And they said, "The Lord has need of it."
And they brought it to Jesus, and they threw their garments on the colt, and put Jesus on it. And as He was going, they were spreading their garments in the road. And as He was now approaching, near the descent of the Mount of Olives, the whole multitude of the disciples began to praise God joyfully with a loud voice for all the miracles which they had seen, saying, "Blessed is the King who comes in the name of the Lord; Peace in heaven and glory in the highest!"
And some of the Pharisees in the multitude said to Him, "Teacher, rebuke Your disciples."
And He answered and said, "I tell you, if these become silent, the stones will cry out!"

And when He approached, He saw the city and wept over it, saying "If you had known in this day; even you, the things which make for peace! But now they have been hidden from your eyes. For the days shall come upon you when your enemies will throw up a bank before you, and surround you, and hem you in on every side, and will level you to the ground and your children within you, and they will not leave in you one stone upon another, because you did not recognize the time of your visitation."
