Isaiah 6:8-13 - Isaiah's Commission From The Lord
8 After this I heard the voice of the LORD, taking advisement on this manner, "Whom shall I send, and who will be our messenger?" Then I said, "Here am I, send me."
9 And so he said, "Go, and tell this people: 'Ye shall hear indeed, but ye shall not understand; ye shall plainly see, and not perceive. 10 Harden the heart of this people, stop their ears, and shut their eyes, that they see not with their eyes, hear not with their ears, and understand not with their heart, and convert and be healed."
11 Then spake I, "LORD, how long?" And he answered, "Until the cities be utterly without inhabiters, and the houses without men, till the land be also desolate, and lie unbuilded. 12 For the LORD shall take the men far away, so that the land shall lie waste. 13 Nevertheless, the tenth part shall remain therein, for it shall convert and be fruitful. And likewise as the Terebinths and Oak trees in winter cast their leaves and yet have their sap in them, so shall the holy seed continue in their substance."
