'Plaster' 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.

Behold, when the wall has fallen, shall it not be said to you, Where is the plaster with which you have plastered it?
