Jezekiel 13:10

10 Because they have caused my people to err, saying, Peace; and there is no peace; and one builds a wall, and they plaster it, —it shall fall.

Jezekiel 13:10 In-Context

8 And therefore say, Thus saith the Lord; Because your words are false, and your prophecies are vain, therefore, behold, I am against you, saith the Lord.
9 And I will stretch forth my hand against the prophets that see false , and those that utter vanities: they shall not partake of the instruction of my people, neither shall they be written in the roll of the house of Israel, and they shall not enter into the land of Israel; and they shall know that I am the Lord.
10 Because they have caused my people to err, saying, Peace; and there is no peace; and one builds a wall, and they plaster it, —it shall fall.
11 Say to them that plaster , It shall fall; and there shall be a flooding rain; and I will send great stones upon their joinings, and they shall fall; and there shall be a sweeping wind, and it shall be broken.
12 And lo! the wall has fallen; and will they not say to you, Where is your plaster wherewith ye plastered ?
