"All the four evangelists take notice of this passage of Christ's riding in triumph into Jerusalem, five days before his death. The passover was on the fourteenth day of the month, and this was the tenth; on which day the law appointed that the paschal lamb should be taken up (Exod. xii. 3), and set apart for that service; on that day therefore Christ our Passover, who was to be sacrificed for us, was publicly showed. So that this was the prelude to his passion. He had lodged at Bethany, a village not far from Jerusalem, for some time; at a supper there the night before Mary had anointed his feet, John xii. 3. But, as usual with ambassadors, he deferred his public entry till some time after his arrival. Our Lord Jesus travelled much, and his custom was to travel on foot from Galilee to Jerusalem, some scores of miles, which was both humbling and toilsome; many a dirty weary step he had when he went about doing good. How ill does it become Christians to be inordinately solicitous about their own ease and state, when their Master had so little of either! Yet once in his life he rode in triumph; and it was now when he went into Jerusalem, to suffer and die, as if that were the pleasure and preferment he courted; and then he thought himself begin to look great."
