'Whitewash' in the Bible
Because, even because they have seduced my people, saying, Peace; and there is no peace; and when one builds up a wall, behold, they plaster it with whitewash:
tell those who plaster it with whitewash, that it shall fall: there shall be an overflowing shower; and you, great hailstones, shall fall; and a stormy wind shall tear it.
So will I break down the wall that you have plastered with whitewash, and bring it down to the ground, so that its foundation shall be uncovered; and it shall fall, and you shall be consumed in its midst: and you shall know that I am Yahweh.
Thus will I accomplish my wrath on the wall, and on those who have plastered it with whitewash; and I will tell you, The wall is no more, neither those who plastered it;
Her prophets have plastered for them with whitewash, seeing false visions, and divining lies to them, saying, Thus says the Lord Yahweh, when Yahweh has not spoken.
