'Genuine' in the Bible

Yet when they were sick,my clothing was sackcloth;I humbled myself with fasting,and my prayer was genuine.

Genuine righteousness leads to life,but pursuing evil leads to death.

But if we say, ‘From men’”—they were afraid of the crowd, because everyone thought that John was a genuine prophet.

So if you have not been faithful with the unrighteous money, who will trust you with what is genuine?
