Jn 19:30,

Jesus prophesied that it would happen on the third day when King Herod said that he would kill Jesus. And by his death, the work of Christ was fully accomplished. (Lk 13:31-32, Jn 19:30)

Lk 13:31 The same day there came certain of the Pharisees, saying unto him, Get thee out, and depart hence: for Herod will kill thee. 32 And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected.

Jn 19:30 When Jesus therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost.
