'Untempered' in the Bible

Because, even because they have seduced my people, saying, Peace; and there was no peace; and one built up a wall, and, lo, others daubed it with untempered morter:

Say unto them which daub it with untempered morter, that it shall fall: there shall be an overflowing shower; and ye, O great hailstones, shall fall; and a stormy wind shall rend it.

So will I break down the wall that ye have daubed with untempered morter, and bring it down to the ground, so that the foundation thereof shall be discovered, and it shall fall, and ye shall be consumed in the midst thereof: and ye shall know that I am the LORD.

Thus will I accomplish my wrath upon the wall, and upon them that have daubed it with untempered morter, and will say unto you, The wall is no more, neither they that daubed it;

And her prophets have daubed them with untempered morter, seeing vanity, and divining lies unto them, saying, Thus saith the Lord GOD, when the LORD hath not spoken.
