The poor too often turn away unheard,
From hearts that shut against them with a sound
That will be heard in heaven. [ Longfellow ]

I was too hasty to condemn unheard; and you perhaps too prompt in your replies. [ Dryden ]

A wasting disease and an unheard-of battalion of fevers have swooped down on the earth. [ Horace ]

The grandest operations, both in nature and in grace, are the most silent and imperceptible. The shallow brook babbles in its passage, and is heard by every one; but the coming on of the seasons is silent and unseen. The storm rages and alarms, but its fury is soon exhausted, and its effects are partial and soon remedied; but the dew, though gentle and unheard, is immense in quantity, and the very life of large portions of the earth. And these are pictures of the operations of grace in the church and in the soul. [ Cecil ]
