Yaro,
This
Study of Matthew at Yashnet.com has a different interpretation from a Jewish point of view. They are Jews who believe in Christ.
Excerpt:
As we see in chapters 21 through 23, Yeshua directed most of his criticism at the religious leaders of the day, who "shut up the kingdom of heaven" for themselves and others, due to their voiding the commandments of God (Torah) through man-made doctrines.
They interpret the story to mean the religious leaders as opposed to Israel as a group.
I was always confused by this story also.
A gentle answer turns away wrath, But a harsh word stirs up anger.
