Jonah 4:11

Should I not spare? -literally “have pity” and so “spare.” God waives for the time the fact of the repentance of Nineveh, and speaks of those on whom man must have pity, those who never had any share in its guilt, the 120,000 children of Nineveh, “I who, in the weakness of infancy, knew not which hand, “the right” or “the left,” is the stronger and fitter for every use.” He who would have spared Sodom “for ten’s sake,” might well be thought to spare Nineveh for the 120,000’s sake, in whom the inborn corruption had not developed into the malice of willful sin. If these 120,000 were the children under three years old, they were 15 (as is calculated) of the whole population of Nineveh.
