Jeremiah 1:6

3 and it is in the days of Jehoiakim son of Josiah, king of Judah, till the completion of the eleventh year of Zedekiah son of Josiah, king of Judah, till the removal of Jerusalem in the fifth month.

4 And there is a word of Jehovah unto me, saying,

5 `Before I form thee in the belly, I have known thee; and before thou comest forth from the womb I have separated thee, a prophet to nations I have made thee.`

6 And I say, `Ah, Lord Jehovah! lo, I have not known -- to speak, for I [am] a youth.`

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.
