'Faithful' in the Bible

I put my brother Hanani, with Hananiah the commander of the fortress, in charge of Jerusalem, for Hananiah was a more faithful and God-fearing man than many [of the others].

“You found his heart to be faithful before You,And You made a covenant with himTo give him the land of the Canaanite,Of the Hittite, of the Amorite,Of the Perizzite, the Jebusite, and the Girgashite—To give it to his descendants.And You have fulfilled Your promise,For You are righteous and just.

I appointed [as treasurers] over the storehouses: Shelemiah the priest, Zadok the scribe, and Pedaiah of the Levites; assisting them was Hanan son of Zaccur, the son of Mattaniah; for they were considered faithful and reliable, and their task was to distribute [supplies] to their brothers (fellow Levites).
