Let favor be showed to the wicked. This is a further explanation of the reason why the righteous had so earnestly desired the coming of God's judgments upon the earth. They had felt that further mercy and long-suffering wine thrown away upon the wicked, and "only did them harm" (Kay).
When "favor was showed them," they did but persist in unrighteousness. In the land of uprightness will he deal unjustly. Even good example does not convert the wicked man. Though he live in a "land of righteousness," where God and his Law are acknowledged, where true religion is professed, where the gospel is preached, he will continue wicked, he will "deal unjustly;" he will not behold—or, consider—the majesty of the Lord.
