Isaiah 6:7-9

Darby Translation

⁷ and he made it touch my mouth, and said, Behold, this hath touched thy lips; and thine iniquity is taken away, and thy sin expiated.

⁸ And I heard the voice of the Lord saying, Whom shall I send, and who will go for us? And I said, Here am I; send me.

⁹ And he said, Go; and thou shalt say unto this people, Hearing ye shall hear and shall not understand, and seeing ye shall see and shall not perceive.
