Nehemiah 13:16 Some men from Tyre, who lived in Jerusalem, were bringing in fish and all kinds of merchandise. They were selling it on the Sabbath to the people of Judah—and in Jerusalem at that!
17 So I confronted the nobles of Judah. “Why are you profaning the Sabbath in this evil way?” I asked. 18 “Wasn’t it just this sort of thing that your ancestors did that caused our God to bring all this trouble upon us and our city? Now you are bringing even more wrath upon Israel by permitting the Sabbath to be desecrated in this way!”
19 Then I commanded that the gates of Jerusalem should be shut as darkness fell every Friday evening, not to be opened until the Sabbath ended. I sent some of my own servants to guard the gates so that no merchandise could be brought in on the Sabbath day. 20 The merchants and tradesmen with a variety of wares camped outside Jerusalem once or twice. 21 But I spoke sharply to them and said, “What are you doing out here, camping around the wall? If you do this again, I will arrest you!” And that was the last time they came on the Sabbath. 22 Then I commanded the Levites to purify themselves and to guard the gates in order to preserve the holiness of the Sabbath. Remember this good deed also, O my God! Have compassion on me according to your great and unfailing love.

Ezra 10:9 Within three days, all the people of Judah and Benjamin had gathered in Jerusalem. This took place on December 19, and all the people were sitting in the square before the Temple of God. They were trembling both because of the seriousness of the matter and because it was raining. 10 Then Ezra the priest stood and said to them: “You have committed a terrible sin. By marrying pagan women, you have increased Israel’s guilt. 11 So now confess your sin to the Lord, the God of your ancestors, and do what he demands. Separate yourselves from the people of the land and from these pagan women.”
12 Then the whole assembly raised their voices and answered, “Yes, you are right; we must do as you say!” 13 Then they added, “This isn’t something that can be done in a day or two, for many of us are involved in this extremely sinful affair. And this is the rainy season, so we cannot stay out here much longer. 14 Let our leaders act on behalf of us all. Let everyone who has a pagan wife come at a scheduled time, accompanied by the leaders and judges of his city, so that the fierce anger of our God concerning this affair may be turned away from us.”

Malachi 4:1 The Lord of Heaven’s Armies says, “The day of judgment is coming, burning like a furnace. On that day the arrogant and the wicked will be burned up like straw. They will be consumed—roots, branches, and all. 2 “But for you who fear my name, the Sun of Righteousness will rise with healing in his wings. And you will go free, leaping with joy like calves let out to pasture. 3 On the day when I act, you will tread upon the wicked as if they were dust under your feet,” says the Lord of Heaven’s Armies.
4 “Remember to obey the Law of Moses, my servant—all the decrees and regulations that I gave him on Mount Sinai for all Israel. 5 “Look, I am sending you the prophet Elijah before the great and dreadful day of the Lord arrives. 6 His preaching will turn the hearts of fathers to their children, and the hearts of children to their fathers. Otherwise I will come and strike the land with a curse.”
