'Faithful' in the Bible

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

and foundest his heart faithful before thee, and madest the 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 to his seed; and thou hast performed thy words, for thou art righteous.

And I made storekeepers over the storehouses: Shelemiah the priest, and Zadok the scribe, and of the Levites, Pedaiah; and subordinate to them, Hanan the son of Zaccur, the son of Mattaniah; for they were esteemed faithful, and their office was to distribute to their brethren.
