'Whitewash' in the Bible

Because, even because they have been guiding my people into error, saying, Peace; when there is no peace; and in the building of a division wall they put whitewash on it:

Say to those who put whitewash on it, There will be an overflowing shower; and you, O ice-drops, will come raining down; and it will be broken in two by the storm-wind.

And when the wall has come down, will they not say to you, Where is the whitewash which you put on it?

So I will let the wall, which you were covering with whitewash, be broken down; I will have it levelled to the earth so that its base is uncovered: it will come down, and destruction will come on you with it; and it will be clear to you that I am the Lord.

So I will let loose my passion on the wall in full measure, and on those who put whitewash on it; and I will say to you, Where is the wall, and where are those who put whitewash on it?

And her prophets have been using whitewash, seeing foolish visions and making false use of secret arts, saying, This is what the Lord has said, when the Lord has said nothing.
