'Understanding' in the Bible

Therefore my people will be deported because of their lack of understanding. Their leaders will have nothing to eat, their masses will have nothing to drink.

Those who think they are wise are as good as dead, those who think they possess understanding.

When its branches get brittle, they break; women come and use them for kindling. For these people lack understanding, therefore the one who made them has no compassion on them; the one who formed them has no mercy on them.

Those who stray morally will gain understanding; those who complain will acquire insight.

The dogs have big appetites; they are never full. They are shepherds who have no understanding; they all go their own way, each one looking for monetary gain.
