Ezekiel 13:10

"Because, even because they have seduced my people, saying Peace, and there is no peace; and when one buildeth up a wall, behold, they daub it with untempered mortar. Say unto them that daub it with untempered mortar, that it shall fall; there shall be an overflowing shower; and ye, O great hailstones, shall fall; and a stormy wind shall rend it. Lo, when the wall is fallen, shall it not be said unto you, Where is the daubing wherewith ye daubed it? Therefore, thus saith the Lord Jehovah: I will even rend it with a stormy wind in my wrath; and there shall be an overflowing shower in mine anger, and great hailstones in wrath to consume it. So will I break down the wall that ye have daubed with untempered mortar, and bring it down to the ground, so that the foundation thereof shall be uncovered; and it shall fall, and ye shall be consumed in the midst thereof: and ye shall know that I am Jehovah. Thus will I accomplish my wrath upon the wall, and upon them that have daubed it with untempered mortar; and I will say unto you, The wall is no more, neither they that daubed it; to wit, the prophets of Israel that prophesy concerning Jerusalem, and that see visions of peace for her, and there is no peace, saith the Lord Jehovah."

THE SECOND DENUNCIATION OF FALSE PROPHETS

The utter lack of integrity among the false prophets is here illustrated by the work of a foolish, incompetent builder who uses worthless mortar in the construction of a wall. We do not know exactly what the "untempered mortar" actually was, but it makes no difference. Whatever it was, it was worthless, and the first shower totally ruined it; but God promised them that it would be no ordinary shower at all, but an "overflowing one" in God's anger, with great hailstones and a tornadic wind. Their wall would fall ... fall ... fall ... come down to the ground... be consumed ... its foundation uncovered ... and even. the builders of it consumed with it!

This is not a reference to any literal wall, but to the rotten, worthless, and unbelieving "prophecies" these sinful men were preaching in place of the true Word of God; and we must add that there is today, in our society, a lot of daubing going on with the same kind of untempered mortar! Keil identified the daubing with untempered mortar as, "A figurative description of deceitful flattery and hypocrisy, the covering up of inward corruption with outward appearances, as in Matthew 23:27, and Acts 23:3."[8]
