Charles Spurgeon Commentary Luke 19:10-11

"For the Son of man came to seek and to save that which was lost. And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and [because] they supposed that the kingdom of God was immediately to appear." — Luke 19:10-11 (ASV)

For the Son of man is come to seek and to save that which was lost. And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and because they thought that the kingdom of God should immediately appear.

Some of them dreamt of a temporal sovereignty with Christ at its head, so he taught them that his kingdom was something very different from that.
