Isaiah 6:7-11 New American Bible, Revised Edition (NABRE)

7. He touched my mouth with it. “See,” he said, “now that this has touched your lips, your wickedness is removed, your sin purged.”

8. Then I heard the voice of the Lord saying, “Whom shall I send? Who will go for us?” “Here I am,” I said; “send me!”

9. And he replied: Go and say to this people:Listen carefully, but do not understand!Look intently, but do not perceive!

10. Make the heart of this people sluggish,dull their ears and close their eyes;Lest they see with their eyes, and hear with their ears,and their heart understand,and they turn and be healed.

11. “How long, O Lord?” I asked. And he replied: Until the cities are desolate,without inhabitants,Houses, without people,and the land is a desolate waste.
