'Unto' in the Bible

A word of Jehovah that hath been unto Zephaniah son of Cushi, son of Gedaliah, son of Amariah, son of Hezikiah, in the days of Josiah son of Amoz, king of Judah:

Therefore, I live, An affirmation of Jehovah of Hosts, God of Israel, Surely, Moab is as Sodom, And the sons of Ammon as Gomorrah, An overrunning of nettles and salt-pits, And a desolation -- unto the age. A residue of My people do seize them, And a remnant of My nation inherit them.

She hath not hearkened to the voice, She hath not accepted instruction, In Jehovah she hath not trusted, Unto her God she hath not drawn near.

For then do I turn unto peoples a pure lip, To call all of them by the name of Jehovah, To serve Him with one shoulder.
