Thus says the Lord of hosts: Render true judgments, show kindness and mercy to one another; do not oppress the widow, the orphan, the alien, or the poor; and do not devise evil in your hearts against one another.
But they refused to listen and turned a stubborn shoulder and stopped their ears in order not to hear. They made their hearts adamant in order not to hear the law and the words that the Lord of hosts had sent by his spirit through the former prophets. Therefore great wrath came from the Lord of hosts.
