Thou shalt not see a fierce people, a people of a deeper speech than thou canst perceive; of a stammering tongue, that thou canst not understand.

Know the Bible

What does Isaiah 33:19 mean?

Isaiah 33:19 says that the people being addressed will no longer see a fierce, intimidating nation—one whose language is so foreign and harsh that it cannot be understood. The verse promises relief from the threat of a strange and frightening enemy.

In this chapter, the prophet Isaiah is speaking to the people of Jerusalem during a time of danger from foreign invaders. The verse highlights the fear caused by enemies who are not only violent but also speak in a way that is completely unfamiliar, adding to the sense of alienation and threat. Isaiah is assuring the people that God will remove this danger and that they will no longer have to face such intimidating outsiders.

The Hebrew behind Isaiah 33:19

  • The word "fierce" (עַזֵּי, ‘azzei) means strong, harsh, or fierce. It emphasizes the intimidating and overwhelming nature of the foreign people.
  • "Deeper speech" (עִמְקֵי, ‘imqei) refers to speech that is deep, obscure, or difficult to understand, highlighting the sense of confusion and distance created by the enemy's language.
  • "Stammering" (לָעֵג, la‘eg) literally means mocking or unintelligible, suggesting speech that sounds like gibberish or is impossible to follow, which increases the sense of being threatened by strangers.

Why Isaiah 33:19 matters

  • This verse clarifies that the threat is not just military but also cultural and psychological—the fear comes from facing people who are both violent and completely foreign in language and custom.
  • Isaiah 33:19 connects to the wider passage by showing the reversal of Jerusalem’s fortunes: where there was once fear and confusion, there will now be safety and understanding.
  • The verse helps readers see that God’s promise of protection includes relief from the anxiety of facing the unknown, not just physical safety from attack.
