But thou, O Lord, art a God full of compassion, and gracious, longsuffering, and plenteous in mercy and truth.
But thou, O Lord, art a God full of compassion, and gracious, long-suffering, and plenteous in mercy and truth - quoted mainly from Exodus 34:6. Here the Psalmist reverts to the same ground of hope as in Psalms 86:5 - God's character as "plenteous in mercy unto all that call upon" Him; not unto the impenitent.
