John Wesley on Matthew 21:5

The daughter of Sion - That is, the inhabitants of Jerusalem: the first words of the passage are cited from Isa 62:11; the rest from Zech 9:9. The ancient Jewish doctors were wont to apply these prophecies to the Messiah. On an ass - The Prince of Peace did not take a horse, a warlike animal. But he will ride on that by and by, Rev 19:11. In the patriarchal ages, illustrious persons thought it no disgrace to make use of this animal: but it by no means appears, that this opinion prevailed, or this custom continued, till the reign of Tiberias. Was it a mean attitude wherein our Lord then appeared? Mean even to contempt! I grant it: I glory in it: it is for the comfort of my soul for the honour of his humility, and for the utter confusion of all worldly pomp and grandeur.
