Ezekiel 13:10

Because, even because they have seduced my people
Who were so by profession; otherwise such who are truly the people of God, though they may be deceived in civil things, yet not in religious matters, at least not totally and finally; in this sense it is impossible to deceive the elect of God; but as false teachers are deceivers, they lie in wait, and use all means to deceive them, and do deceive nominal professors, which is resented by the Lord; and this is given as a reason of their punishment; and which is doubled, as in ( Leviticus 26:43 ) ; to show the heinousness of their sin, and the certainty of their punishment: saying, peace, and [there was] no peace;
giving out that peace would be made with the king of Babylon; that the captives would return to their own land, where, with those that were in it, they would enjoy great prosperity; when no such thing came to pass, nor would; but the contrary was certain, by the predictions of the true prophets sent by the Lord: and one built up a wall;
one of the false prophets, and of the chief of them, gave out that Jerusalem would continue a walled city, and abide firm and impregnable against the Chaldean army, and would never be taken: and, lo, others daubed it with untempered [mortar];
others of the false prophets, observing that what the first had delivered out was pleasing to the people, not only assented to it, but strongly affirmed it; and, with colourings and specious arguments, made it look more plausible and probable; when, alas! the whole was no other than like putting a parcel of loose stones or bricks together, and throwing some slushy stuff upon them, as, moistened sand without lime, or clay without straw, as the Targum and Vulgate Latin versions render it; which would never cement the bricks or stones together. R. Joseph Kimchi interprets it of bricks not burnt: so false teachers imitate the true ministers of the word, in preaching peace; but then they do not direct aright where it is to be had, which is only in Christ; or the proper persons, sinners pressed with the guilt of sin, and seeking for ease and peace in a right way; but publish it to those to whom it does not belong, for there is no peace to the wicked; and put them upon making peace themselves by their own works of righteousness, and their legal repentance, and outward humiliation; or promise it to them, though they have no faith in Christ, and are not sensible of their sin and danger: these men are builders, but not wise master builders; they do not build upon the foundation Christ, but build up a wall without him; leaving him out of the building who is the chief corner stone; deliver out some loose and unconnected doctrines, that are not according to the Scriptures, nor consistent with each other; and encourage the people to perform some loose duties and cold services, without the cement of faith and love; and which is no other than building upon the sand, or with it; though they fancy it to be a wall, a shelter, and protection to them, from the wrath and justice of God, and by which they shall climb up to heaven; which will prove a bowing wall, and a tottering fence; and in these mistakes they are buoyed up by false teachers, and are flattered as being in a fair way for eternal happiness.
