Isaiah 6:9-13 New American Bible, Revised Edition (NABRE)

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.

12. Until the Lord sends the people far away,and great is the desolation in the midst of the land.

13. If there remain a tenth part in it,then this in turn shall be laid waste;As with a terebinth or an oakwhose trunk remains when its leaves have fallen. Holy offspring is the trunk.
