13:8-9 The Lord told these false prophets that He opposed them for what they had done. He would act against them by removing them from positions of influence among His people, depriving them of the rights of citizenship in Israel (cf. Ezra 2:62; Luke 10:20; Rev. 3:5; 20:15), and preventing them from returning to the Promised Land. They had failed as "watchmen"over the house of Israel (cf. 3:16-21). The fulfillment of these judgments would prove to them that Yahweh was Lord (cf. Exod. 7:5).
13:10-11 Judgment would come on them for misleading the Lord's people by falsely predicting peace when no peace was coming. There are two interpretations of the references to whitewashing, the literal and the metaphorical.
The literal interpretation understands God to be saying that when the residents of Jerusalem built their walls (Heb. hayis, a flimsy partition) and houses, believing that they were secure, the false prophets supported their efforts by adding the whitewash. They should have warned them to prepare for coming judgment rather than helping them beautify the walls of their homes. The coming divine judgment would descend on Jerusalem like a rainstorm with hailstones and violent winds and destroy their beautifully whitewashed walls.203
The metaphorical interpretation, which most commentators take and which I prefer, understands God to be saying that these false prophets were putting a good front on the situation in Jerusalem, saying peace rather than judgment was coming. They were compounding Israel's difficulties by hiding problems that needed to be exposed and corrected. Ezekiel was to tell them that invasion would come, like a rainstorm with hailstones and violent winds, and that their facade of a future for the people would then come crashing down (cf. Matt. 7:24-29).
"The false prophets were compared to those who build an unsafe wall and cover up its defects. The untempered mortar [AV] was actually whitewash, which is useless for strengthening insecure walls. Smooth words of false messengers hid from the people the actual seriousness of their spiritual condition. To daub with untempered mortar [or plaster with whitewash], in the metaphorical sense, is to flatter, to use hypocrisy. When the false prophets confirmed the people in their evil ways, by their approval they were whitewashing the flimsy spiritual structure of Israel."204
13:12 When the walls, or the scenario of the future that the false prophets had painted, had collapsed, the people would ask a question. They would question the materials out of which they constructed the wall, either the literal wall or the wall of false speculation. It had proved inadequate and unreliable.
13:13-14 The Lord promised to send a violent storm of judgment on His people in Jerusalem because of His anger against them and to destroy the people's homes and the false prophets' vision of the future. Then the foundations of their homes and the false prophets' vision would lie exposed for all to see, and the false prophets themselves would perish in the judgment. Then they would know that the Lord was God.
13:15-16 The Lord would destroy both the people's homes, or the false vision of the future that these prophets painted, as well as the prophets themselves, those who promised peace to Jerusalem when no peace was coming (cf. Matt. 18:7).
"It is a common failing for preachers to want to speak pleasing and appeasing words to their people, but if they are to be true to their calling they must be sure to receive and to impart nothing but God's clear word, irrespective of the consequences. When church leaders encourage their people in sub-Christian standards or unbiblical ways they make themselves doubly guilty."205
