'Whitewash' in the Bible

It is definitely because they have seduced My people, saying, ‘Peace,’ when there is no peace, and because when one builds a [flimsy] wall, behold, these [lying] prophets plaster it over with whitewash;

so tell those who plaster it with whitewash, that it will fall! A flooding rain [of judgment] will come, and you, O [great] hailstones, will fall; and a violent wind will tear the wall apart.

So I will tear down the wall which you have plastered with whitewash and bring it down to the ground, so that its foundations will be exposed; when it falls, you will perish in its midst. And you shall know and understand fully that I am the Lord.

Thus I will expend My wrath on the wall and on those who have plastered it with whitewash and I will say to you, ‘The wall is gone and its plasterers are gone,

Her prophets have smeared whitewash for them, seeing false visions and divining lies for them, saying, ‘Thus says the Lord God’—when the Lord has not spoken.
