With proud heart …
With proud heart (Isa. 16:6) ...
Wearing yourselves out in serving is useless (v. 12).
Coming to his sanctuary to pray is useless (v. 12).
Boasting is false (v. 6).
The Lord stops the voice of joy and gladness from the proud heart (v. 10).
And the Lord turns that joy and gladness into wail and moan (v. 7) and tears and weeping (v. 9).
