Hypocritical Repentance and Divine Compassion

Psalms 78:34-39

If He slew them, then they sought Him, And turned back, and sought God earnestly,

And they remember that God is their rock, And God Most High their redeemer.

And--they deceive Him with their mouth, And with their tongue do lie to Him,

And their heart hath not been right with Him, And they have not been stedfast in His covenant.

And He--the Merciful One, Pardoneth iniquity, and destroyeth not, And hath often turned back His anger, And waketh not up all His fury.

And He remembereth that they are flesh, A wind going on--and it returneth not.
