'Faithful' in the Bible

That I gave my brother Hanani, and Hananiah the ruler of the palace, charge over Jerusalem: for he was a faithful man, and feared God above many.

And foundest his heart faithful before thee, and madest a covenant with him to give the land of the Canaanites, the Hittites, the Amorites, and the Perizzites, and the Jebusites, and the Girgashites, to give it, I say, to his seed, and hast performed thy words; for thou art righteous:

They refused to listenand did not remember Your wondersYou performed among them.They became stiff-necked and appointed a leaderto return to their slavery in Egypt.But You are a forgiving God,gracious and compassionate,slow to anger and rich in faithful love,and You did not abandon them.

And I made treasurers over the treasuries, Shelemiah the priest, and Zadok the scribe, and of the Levites, Pedaiah: and next to them was Hanan the son of Zaccur, the son of Mattaniah: for they were counted faithful, and their office was to distribute unto their brethren.

Remember me, my God, concerning this, and do not erase my faithful deeds that I have undertaken for the Temple of my God, and for its services.

Then I instructed the Levites to purify themselves and guard the gates in order to keep the Sabbath day holy.Remember me for this also, my God, and look on me with compassion in keeping with Your abundant, faithful love.
