14 Jesus found a young donkey and sat on it, as it is written: 15 "Do not be afraid, Daughter Zion; see, your king is coming, seated on a donkey's colt."[1] 16 At first his disciples did not understand all this. Only after Jesus was glorified did they realize that these things had been written about him and that these things had been done to him.

Commentary on John 12:12-19

(Read John 12:12-19)

Christ's riding in triumph to Jerusalem is recorded by all the evangelists. Many excellent things, both in the word and providence of God, disciples do not understand at their first acquaintance with the things of God. The right understanding of spiritual nature of Christ's kingdom, prevents our misapplying the Scriptures which speak of it.
