CCC 557

"When the days drew near for him to be taken up [Jesus] set his face to go to Jerusalem." Lk 9:51; cf. Jn 13:1. By this decision he indicated that he was going up to Jerusalem prepared to die there. Three times he had announced his Passion and Resurrection; now, heading toward Jerusalem, Jesus says: "It cannot be that a prophet should perish away from Jerusalem." Lk 13:33; cf. Mk 8:31-33; 9:31-32; 10:32-34.
