9 Thus says the Lord of hosts: Render true judgments, show kindness and mercy to one another; 10 do not oppress the widow, the orphan, the alien, or the poor; and do not devise evil in your hearts against one another. 11 But they refused to listen, and turned a stubborn shoulder, and stopped their ears in order not to hear. 12 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. 13 Just as, when I called, they would not hear, so, when they called, I would not hear, says the Lord of hosts, 14 and I scattered them with a whirlwind among all the nations that they had not known. Thus the land they left was desolate, so that no one went to and fro, and a pleasant land was made desolate.

Commentary on Zechariah 7:8-14

(Read Zechariah 7:8-14)

God's judgements upon Israel of old for their sins, were written to warn Christians. The duties required are, not keeping fasts and offering sacrifices, but doing justly and loving mercy, which tend to the public welfare and peace. The law of God lays restraint upon the heart. But they filled their minds with prejudices against the word of God. Nothing is harder than the heart of a presumptuous sinner. See the fatal consequences of this to their fathers. Great sins against the Lord of hosts, bring great wrath from his power, which cannot be resisted. Sin, if regarded in the heart, will certainly spoil the success of prayer. The Lord always hears the cry of the broken-hearted penitent; yet all who die impenitent and unbelieving, will find no remedy or refuge from miseries which while here they despised and defied, but which they then will not be able to bear.
