'Lesson' in the Bible

He took the elders of the city, and thorns of the wilderness and briars, and with them he punished the men of Succoth.

When the scoffer is punished, the naive [observes the lesson and] becomes wise;But when the wise and teachable person is instructed, he receives knowledge.

Therefore He poured out on Israel the heat of His angerAnd the fierceness of battle;And engulfed him in fire,Yet he did not recognize [the lesson of repentance which the Assyrian conquest was intended to teach];It burned him, but he did not take it to heart.
