Ezekiel 13:6

(Versed 4 et sequentia) Your prophets, Israel, will be like foxes in the desert. You did not go up to face the enemy or build a wall for the house of Israel to stand firm in battle on the day of the Lord. They see false visions and speak deceptive divinations, saying, 'The Lord declares,' when the Lord has not sent them; yet they hope for the fulfillment of their words. Have you not seen a false vision and uttered a lying divination when you say, 'The Lord declares,' though I have not spoken?' LXX: Like foxes in the deserts are your prophets, O Israel ((Add. they were or will be)). They did not stand in the firmament, and they gathered flocks over the house of Israel. Those who say in the day of the Lord did not rise: seeing falsehoods, divining vanities, those who say, says the Lord, and the Lord did not send them: and they began to stir up discourse. Did you not see false visions, and speak vain divinations? And you said, says the Lord, and I did not speak. Let us first speak according to the Hebrew. The prophets of Israel are like foxes, committing thefts of domestic birds every day: those who live, according to Aquila and the Septuagint, in the deserts; according to Symmachus and Theodotion, in walls and ruins: who cannot advance opposite, nor oppose a wall for the house of Israel. We read that Aaron stood in the middle against the fire devouring the people of Israel, and opposed a wall for the salvation of the people (Num. XVI). It is also said of Jeremiah, 'Do not confront the Lord, nor stand against His wrath with persevering prayer' (Jer. 7). Just as a wall is set against an enemy and is usually met head-on by the adversary, so the will of God is weakened by the prayers of the saints. Therefore, Moses is also told, 'Let me alone, and I will destroy this people' (Exod. 32:10), which shows that he had the power to hold back. […]

All that they want is false, and they can never see the truth. Take an example. To read the Scripture and to hear something other than what is written is to have an untruthful picture of Scripture; but to hear Scripture and interpret it in accordance with the truth, that is to see the truth.

To such men it is rightly said through the prophet: "You have not gone up against the enemy, nor have you set up a wall for the house of Israel, to stand in battle on the day of the Lord." To go up against the enemy is to oppose with the free voice of reason any powers that act wickedly. And we stand in battle on the day of the Lord for the house of Israel and set up a wall if we defend the faithful and innocent against the injustice of the perverse with the authority of justice. Because the hireling does not do this, when he sees the wolf coming, he flees.

Whence it is well said to Ezekiel, "Take unto thee a tile, and thou shalt lay it before thee, and pourtray upon it the dry Jerusalem." And immediately it is subjoined, "And thou shalt lay siege against it, and build forts, and cast a mount, and set camps against it, and set battering rams against it round about. And do thou take unto thee an iron frying-pan, and thou shalt set it for a wall of iron between thee and the city." But although the ruler may nicely insinuate all these things, he procures not for himself lasting absolution, unless he glow with a spirit of jealousy against the delinquencies of all and each. For by the frying-pan is denoted a frying of the mind, and by iron the hardness of reproof.

When these pretenders are found to be deceivers atheists and infidels will thence infer, They are all so. The Lord has not sent them; for though crafty enough in other things like the foxes, and very wise for the world, yet they are foolish prophets and have no experimental acquaintance with the things of God.
