Isaías 51

Isaías 51:17

Anger, which is called "the cup in the hand of the Lord" and "the cup of falling that is drained," is in proportion to transgressions, even though he abates to all some of what is their due and dilutes with compassion the unmixed draught of his wrath. For he inclines from severity to indulgence toward those who accept chastisement with fear, and who after a slight affliction conceive and are in pain with conversion and bring forth the perfect spirit of salvation. But he nevertheless reserves the dregs, the last drop of his anger, that he may pour it out entire on those who, instead of being healed by his kindness, grow obdurate, like the hardhearted Pharaoh. — ON HIS FATHER'S SILENCE, ORATION 16:4
