Albert Barnes Commentary Luke 19:3

"And he sought to see Jesus who he was; and could not for the crowd, because he was little of stature." — Luke 19:3 (ASV)

Who he was. Rather, what sort of person he was, or how he appeared. He had that curiosity which is natural to people to see one of whom they have heard much. It would seem, also, that in this case mere curiosity led to his conversion and that of his family. (Compare to 1 Corinthians 14:23–25). God makes use of every principle—of curiosity, or sympathy, or affection, or hope, or fear—to lead people in the way of salvation, and to impress truth on the minds of sinners.

The press. The crowd; the multitude that surrounded Jesus. Earthly princes are often borne in splendid equipages, or even carried, as in Eastern nations, in palanquins on the shoulders of men. Jesus mingled with the multitude, not seeking distinctions of that sort, and perhaps, in appearance, not distinguished from thousands that followed him.

Little of stature. Short. Not a tall man.
