Young's Literal Translation

⁷ And Jehovah saith unto me, `Do not say, I [am] a youth, for to all to whom I send thee thou goest, and all that I command thee thou speakest.

⁸ Be not afraid of their faces, for with thee [am] I to deliver thee, -- an affirmation of Jehovah.'

⁹ And Jehovah putteth forth His hand, and striketh against my mouth, and Jehovah saith unto me, `Lo, I have put my words in thy mouth.
