Isaiah 6:6-8 Young's Literal Translation (YLT)
6 And flee unto me doth one of the seraphs, and in his hand a burning coal, (with tongs he hath taken [it] from off the altar,)
7 and he striketh against my mouth, and saith: `Lo, this hath stricken against thy lips, And turned aside is thine iniquity, And thy sin is covered.'
8 And I hear the voice of the Lord, saying: `Whom do I send? and who doth go for Us?' And I say, `Here [am] I, send me.'
