Psalms 66:19

[But] verily God hath heard [me]
So that it was a plain case that he had not regarded iniquity in his heart; had not lived a vicious course of life, nor was an hypocrite; otherwise God would not have heard his prayer; whereas he had, and which is confirmed in the following clause;

he hath attended to the voice of my prayer;
which is an instance of the grace and condescension of God, and showed in what high favour the psalmist was with the Lord, and what regard he had unto him; and therefore could not be the man his enemies represented him to be.
