'Insightful' in the Bible

I am more insightful than my teachers, because your decrees are my meditations.

A house and self-sufficiency are a father's inheritance, but from the LORD comes an insightful wife.

Insightful people will impart understanding to many, though they'll fall by sword, by fire, by captivity, and as war booty for a while.

Some of the insightful will fall so they may be refined, purged, and purified until the time of the end, since it will surely come about.'"

Many will be purified, cleansed, and refined, though the wicked will continue to act wickedly, and none of the wicked will understand. Nevertheless, the insightful will understand.
