Woe to you: This is a distinct warning about God's judgment.
hypocrites!: In English, hypocrisy means a contradiction between what is real and what seems to be real. In the Bible, it means misunderstanding God's will, misleading others, and facing God's judgment. This often includes: desire for fame and power (Matthew 23:5–12), misuse of teaching authority, false teachings (23:13–22), and focusing on minor ethical details (23:23–28).
A suitable English word for these behaviors is heresy. The Pharisees and religious teachers showed these traits. As the Christian church grew, these traits continued to appear (for example, 1 Timothy 4:1–3; 2 Peter 2:1–22). So God's children must always be on guard against them (James 4:7–10; 1 Peter 2:1–3).
you shut the kingdom: This comes through their false teachings and opposition to Jesus (see Matthew 9:32–34; 12:22–37; 15:12–14; 21:15; John 9:13–34). The Jewish religious teachers and Pharisees stopped others from hearing and believing the truth about the Messiah.
