Verse:
Isaiah 6:6-10 New Revised Standard Version Updated Edition
6 Then one of the seraphs flew to me, holding a live coal that had been taken from the altar with a pair of tongs. 7 The seraph[a] touched my mouth with it and said, “Now that this has touched your lips, your guilt has departed and your sin is blotted out.” 8 Then 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 say to this people:
‘Keep listening, but do not comprehend;
keep looking, but do not understand.’
10 Make the mind of this people dull,
and stop their ears,
and shut their eyes,
so that they may not look with their eyes
and listen with their ears
and comprehend with their minds
and turn and be healed.”
