What prayer and supplication soever
On account of any of the above things, or any other:
which shall know every man the plague of his own heart;
be sensible of his sin as the cause of his distress, and own it, though ever so privately committed, which none knows but God and his own heart; and which may be only an heart sin, not actually committed; as all sin is originally in the heart, and springs from it, that is the source of all wickedness; it may respect the corruption of nature, indwelling sin, which truly deserves this name, and which every good man is led to observe, confess, and bewail, ( Psalms 51:4 Psalms 51:5 ) . In ( 2 Chronicles 6:29 ) it is,
shall know his own sore and his own grief;
what particularly affects him, and gives him pain and sorrow, as every man best knows his own affliction and trouble, and so can best represent his own case to the Lord:
and spread forth his hands towards this house;
pray with his face towards it, and his hands spread out, a prayer gesture, and what was now used by Solomon, ( 1 Kings 8:22 ) .
