At first his disciples did not understand this; but when Jesus was glorified, they remembered that these things had been written about him, and that these things had been done to him.
In context
14Jesus found a young donkey and mounted it, as it is written: 15“Do not be afraid, daughter of Zion: look, your king is coming, seated on a donkey’s colt.” 16At first his disciples did not understand this; but when Jesus was glorified, they remembered that these things had been written about him, and that these things had been done to him. 17The crowd that had been with him when he called Lazarus from the tomb and raised him from the dead kept telling what they had seen. 18That was also why the crowd went out to meet him: they had heard that he had performed this sign.
