'Diligently' in the Bible

Greet Tryphaena and Tryphosa, who have worked hard for the Lord. Greet my dear friend Persis, who has toiled diligently for the Lord.

Instead, when he arrived in Rome he searched diligently for me and found me.

Now without faith it is impossible to please God, for whoever comes to him must believe that he exists and that he rewards those who diligently search for him.
