'Act' in the Bible

So do the wise [really] have an advantage over fools? {Can the poor [really] gain anything by knowing how to act in front of others}?

Do not be excessively righteous, and do not act excessively wise, lest you destroy yourself.

Do not act excessively wicked, and do not be a fool, lest you die before your time.

Because the sentence against a criminal act is not carried out quickly, the heart of people is filled with the desire to commit crime.

For God will bring every act to judgment, including every hidden thing, whether good or evil.
