'Observers' in the Bible

for these nations whom thou art possessing, unto observers of clouds, and unto diviners, do hearken; and thou -- not so hath Jehovah thy God suffered thee.

I have hated the observers of lying vanities, And I toward Jehovah have been confident.

And ye, ye do not hearken unto your prophets, and unto your diviners, and unto your dreamers, and unto your observers of clouds, and unto your sorcerers who are speaking unto you, saying, Ye do not serve the king of Babylon, --

And have cut off sorcerers out of thy hand, And observers of clouds thou hast none.
